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⋯π contacts, with no π–π 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.
