Abstract Two new complexes, [Ag(μ2-admtrz)($ C_{6} %$ H_{5} $COO)]2·$ 2H_{2} $O (1) and {[$ Ag_{3} $(μ3-admtrz)2($ NO_{3} $)2]($ NO_{3} $)}n (2) (admtrz = 3,5-dimethyl-4-amino-1,2,4-triazole) have been synthesized and characterized. The compounds crystallize in the monoclinic system P$ 2_{1} $/n space group for 1 and in the orthorhombic system Fdd2 for 2. Single crystal X-ray analysis reveals that compound 1 assumes a three-dimensional structure via hydrogen-bonding interactions in which each Ag(І) ion is coordinated by two nitrogen atoms from the ligand admtrz and one oxygen atom from $ C_{6} %$ H_{5} %$ COO^{−} $ anion. While for two-dimensional bilayer cationic framework 2, there consists three-coordinated and two-coordinated silver centers, and part $ NO_{3} $− anions participate to coordinate with Ag(І) ions.
