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.
标题化合物[Zn(CH₃COO)₂(C₁₂H₁₂N₂)]的分子结构由孤立分子组成，这些分子被一个二重旋转轴平分，该轴穿过Zn(II)阳离子，并通过中心C-C键将有机碱平分。Zn(II)离子由来自一个芳香碱分子的两个N原子和来自两个对称相关的双齿乙酸根阴离子的四个O原子配位，它们不对称配位[Zn-O距离为2.058(2)和2.362(3) Å]，而两个Zn-N键距离由于对称性而相等[2.079(2) Å]。晶体结构由许多弱的C-H⋯O相互作用和C-H⋯π接触支撑，不存在π-π相互作用，主要受到取代甲基和相对分子取向的阻碍。结果是形成了一个三维结构，其中每个分子与八个不同的相邻分子相连。
