Abstract

The mol-ecular structure of the title compound, [Zn(CH(3)COO)(2)(C(12)H(12)N(2))], consists of isolated mol-ecules bis-ected by a twofold rotation axis which goes through the Zn(II) cation and halves the organic base through the central C-C bond. The Zn(II) ion is coordinated by two N atoms from one mol-ecule of the aromatic base and four O atoms from two bidentate, symmetry-related acetate anions, which coordinate asym-metrically [Zn-O distances of 2.058 (2) and 2.362 (3) Å], while the two Zn-N bond distances are equal as imposed by symmetry [2.079 (2) Å]. The crystal structure is supported by a number of weak C-H⋯O inter-actions and C-H⋯π contacts, with no π-π inter-actions present, mainly hindered by the substituent methyl groups and the relative mol-ecular orientation. The result is a three-dimensional structure in which each mol-ecule is linked to eight different neighbors.
