In the centrosymmetric title binuclear complex, [Zn(2)(C(8)H(7)O(2))(4)(C(7)H(10)N(2))(2)], the Zn atoms [Zn⋯Zn = 3.0287 (6) Å] are bridged by four 4-methyl-benzoate ligands. The four nearest O atoms around each Zn(II) atom form a distorted square-planar arrangement with the distorted square-pyramidal coordination completed by the pyridine N atom of the 4-(dimethyl-amino)pyridine ligand. In the crystal structure, weak inter-molecular C-H⋯O inter-actions link the mol-ecules into infinite chains. The chains are further linked by weak C-H⋯π inter-actions, forming a three-dimensional network.
在中心对称的标题双核配合物[Zn₂(C₈H₇O₂)₄(C₇H₁₀N₂)₂]中,锌原子[Zn⋯Zn = 3.0287 (6) Å]由四个4-甲基苯甲酸酯配体桥连。每个Zn(II)原子周围的四个最近邻O原子形成一个扭曲的平面正方形排列,4-(二甲基氨基)吡啶配体的吡啶N原子完成扭曲的四方锥配位。在晶体结构中,弱的分子间C-H⋯O相互作用将分子连接成无限链。这些链通过弱的C-H⋯π相互作用进一步连接,形成三维网络。
