The molecular structure of the title compound, [Zn(CH3COO)2(C12H12N2)], consists of isolated molecules bisected by a twofold rotation axis which goes through the ZnII cation and halves the organic base through the central C?C bond. The ZnII ion is coordinated by two N atoms from one molecule of the aromatic base and four O atoms from two bidentate, symmetry-related acetate anions, which coordinate asymmetrically [Zn?O distances of 2.058 (2) and 2.362 (3) A ˚ ], while the two Zn?N bond distances are equal as imposed by symmetry [2.079 (2) A ˚ ]. The crystal structure is supported by a number of weak C?H O interactions and C?H contacts, with no ? interactions present, mainly hindered by the substituent methyl groups and the relative molecular orientation. The result is a three-dimensional structure in which each molecule is linked to eight different neighbors.
