| Popis: | The reaction of 2-methylthio-5-amino-1,3,4-thiadiazole (Me-SNTD; C3H5N3S2) with copper(II) acetate monohydrate [Cu(OAc)2·H2O; C4H8CuO5] resulted in the formation of the title binuclear compound, [Cu2(C2H3O2)4(C3H5N3S2)2] or [Cu2(OAc)4(Me-SNTD)2]. The structure has triclinic (P \overline{1}) 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 carboxylate groups. Each Cu atom is further coordinated to the N atom of an Me-SNTD molecule and exhibits a Jahn–Teller-distorted octahedral geometry. The dimers are connected into infinite chains by hydrogen bonds between the NH (Me-SNTD) and the carboxylate groups of neighbouring molecules, generating an R22(12) ring motif. The molecules are further linked by C—H...π interactions between the thiadiazole rings and the methyl groups of the acetate units. |
