| 520 | |a The influence of pivalic acid on the triangular metal cluster (Cp"2Cr"2SCMe"3)(μ"3-S)"2Co(CO)"2 (II) and its unstable precursor with a probable structure (Cp"2Cr"2SCMe"3)"2(μ"3-S)"2Co(CO)"3 (A) has been studied. An X-ray study has shown that A transforms into an antiferromagnetic ^*^* pseudotetrahedral cluster Cp"3Cr"3(μ"3-S)"3(μ"3-O)Co(CO)"3 . Me"3CCOOH . 0.5C"6H"6(III). The base of the cluster is an isosceles metal triangle, Cp"3Cr"3, which is capped by the tridentate bridging sulphur atom (CrCr 2.692(7), 2.868(8) and 2.884(8) Å, av. CrS 2.26(1) Å). The short CrCr bond is bridged by an oxygen atom, and the long bonds have sulphide bridges which in their turn are weakly bonded to the Co(CO)"3 group (CoO 2.16(2), CoS 2.47(1) and 2.48(1) Å). In addition, the μ"3-O bridging atom forms a hydrogen bond with the HOOCCMe"3 molecule, while the Co atom is situated at weakly-bonding distances from the Cr^I^I^I atoms (CoCr 3.216(6), 3.238(6) and 2.892(6) Å). The transformation of cluster II in the reaction with Me"3CCOOH leads to the antiferromagnetic cluster (Cp"2Cr"2SCMe"3)"2(μ"3-S)"4Co (IV), which according to an X-ray structural study, has a distorted bow-tie framework Cr"4Co with the central Co^I^I atom surrounded also by four μ"3-bridging sulphide atoms. The angle formed by the planes of the Cr"2Co metal triangles is equal to 85.40^o. The bond lengths between pairs of chromium atoms in different triangles are almost equal (2.679(2) and 2.665(2) Å) and close to the length of the CrCr bond in the initial cluster II. At the same time, CoCr bonds in one of the triangles (2.776(2) and 2.774(2) Å) are noticeably shorter than in the other (2.809(2) and 2.959(2); all these values exceed, however, the length of the ordinary CoCr bond (2.59 Å) found in II.The CoS bonds are also elongated (up to 2.26 Å). It is proposed that elongation of CoCr bonds in III and IV (as well as CoO in III) results from an excessive number of electrons in the metal framework as compared to the number of corresponding bonding orbitals. | ||

An X-ray study has shown that A transforms into an antiferromagnetic ^*^* pseudotetrahedral cluster Cp"3Cr"3(μ"3-S)"3(μ"3-O)Co(CO)"3 . Me"3CCOOH . 0.5C"6H"6(III). The base of the cluster is an isosceles metal triangle, Cp"3Cr"3, which is capped by the tridentate bridging sulphur atom (CrCr 2.692(7), 2.868(8) and 2.884(8) Å, av. CrS 2.26(1) Å). The short CrCr bond is bridged by an oxygen atom, and the long bonds have sulphide bridges which in their turn are weakly bonded to the Co(CO)"3 group (CoO 2.16(2), CoS 2.47(1) and 2.48(1) Å). In addition, the μ"3-O bridging atom forms a hydrogen bond with the HOOCCMe"3 molecule, while the Co atom is situated at weakly-bonding distances from the Cr^I^I^I atoms (CoCr 3.216(6), 3.238(6) and 2.892(6) Å). The transformation of cluster II in the reaction with Me"3CCOOH leads to the antiferromagnetic cluster (Cp"2Cr"2SCMe"3)"2(μ"3-S)"4Co (IV), which according to an X-ray structural study, has a distorted bow-tie framework Cr"4Co with the central Co^I^I atom surrounded also by four μ"3-bridging sulphide atoms. The angle formed by the planes of the Cr"2Co metal triangles is equal to 85.40^o. The bond lengths between pairs of chromium atoms in different triangles are almost equal (2.679(2) and 2.665(2) Å) and close to the length of the CrCr bond in the initial cluster II. At the same time, CoCr bonds in one of the triangles (2.776(2) and 2.774(2) Å) are noticeably shorter than in the other (2.809(2) and 2.959(2); all these values exceed, however, the length of the ordinary CoCr bond (2.59 Å) found in II.The CoS bonds are also elongated (up to 2.26 Å). It is proposed that elongation of CoCr bonds in III and IV (as well as CoO in III) results from an excessive number of electrons in the metal framework as compared to the number of corresponding bonding orbitals.</subfield></datafield><datafield tag="533" ind1=" " ind2=" "><subfield code="f">Elsevier Journal Backfiles on ScienceDirect 1907 - 2002</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Eremenko, I.L.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Pasynskii, A.A.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Gasanov, G.S.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Orazsakhatov, B.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Struchkov, Y.T.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Shklover, V.E.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">in</subfield><subfield code="t">Journal of Organometallic Chemistry</subfield><subfield code="d">Amsterdam : Elsevier</subfield><subfield code="g">275(1984), 1, Seite 71-81</subfield><subfield code="w">(DE-627)NLEJ174930496</subfield><subfield code="w">(DE-600)1491530-3</subfield><subfield code="x">0022-328X</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:275</subfield><subfield code="g">year:1984</subfield><subfield code="g">number:1</subfield><subfield code="g">pages:71-81</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">http://linkinghub.elsevier.com/retrieve/pii/0022-328X(84)80580-X</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_H</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">ZDB-1-SDJ</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_NL_ARTICLE</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">275</subfield><subfield code="j">1984</subfield><subfield code="e">1</subfield><subfield code="h">71-81</subfield></datafield></record></collection>

It is proposed that elongation of CoCr bonds in III and IV (as well as CoO in III) results from an excessive number of electrons in the metal framework as compared to the number of corresponding bonding orbitals.</subfield></datafield><datafield tag="533" ind1=" " ind2=" "><subfield code="f">Elsevier Journal Backfiles on ScienceDirect 1907 - 2002</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Eremenko, I.L.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Pasynskii, A.A.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Gasanov, G.S.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Orazsakhatov, B.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Struchkov, Y.T.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Shklover, V.E.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">in</subfield><subfield code="t">Journal of Organometallic Chemistry</subfield><subfield code="d">Amsterdam : Elsevier</subfield><subfield code="g">275(1984), 1, Seite 71-81</subfield><subfield code="w">(DE-627)NLEJ174930496</subfield><subfield code="w">(DE-600)1491530-3</subfield><subfield code="x">0022-328X</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:275</subfield><subfield code="g">year:1984</subfield><subfield code="g">number:1</subfield><subfield code="g">pages:71-81</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">http://linkinghub.elsevier.com/retrieve/pii/0022-328X(84)80580-X</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_H</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">ZDB-1-SDJ</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_NL_ARTICLE</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">275</subfield><subfield code="j">1984</subfield><subfield code="e">1</subfield><subfield code="h">71-81</subfield></datafield></record></collection>
