Abstrakt: The reaction of 2-methyl-thio-5-amino-1,3,4-thia-diazole (Me-SNTD; C 3 H 5 N 3 S 2 ) with copper(II) acetate monohydrate [Cu(OAc) 2 ·H 2 O; C 4 H 8 CuO 5 ] resulted in the formation of the title binuclear compound, [Cu 2 (C 2 H 3 O 2 ) 4 (C 3 H 5 N 3 S 2 ) 2 ] or [Cu 2 (OAc) 4 (Me-SNTD) 2 ]. The structure has triclinic ( P ) symmetry with a crystallographic inversion centre located at the midpoint of the line connecting the Cu atoms in the dimer. These two Cu atoms of the dimer [Cu⋯Cu = 2.6727 (6) Å] are held together by four carboxyl-ate groups. Each Cu atom is further coordinated to the N atom of an Me-SNTD mol-ecule and exhibits a Jahn-Teller-distorted octa-hedral geometry. The dimers are connected into infinite chains by hydrogen bonds between the NH (Me-SNTD) and the carboxyl-ate groups of neighbouring mol-ecules, generating an R 2 2 (12) ring motif. The mol-ecules are further linked by C-H⋯π inter-actions between the thia-diazole rings and the methyl groups of the acetate units.
