The title compound, [Zn(C(7)H(4)BrO(2))(2)(C(10)H(14)N(2)O)(2)(H(2)O)(2)], is a monomeric complex with the Zn(II) atom lying on an inversion center. It contains two 4-bromo-benzoate, two diethyl-nicotinamide ligands and two water mol-ecules, all of which are monodentate. The four O atoms in the equatorial plane around the Zn atom form a slightly distorted square-planar arrangement, while the distorted octa-hedral geometry is completed by two N atoms in the axial positions. The methyl group of one of the ethyl groups is disordered over two positions, with occupancies of ca 0.65 and 0.35. The two aromatic rings are oriented at an angle of 77.22 (14)°. In the crystal structure, O-H⋯O hydrogen bonds link the mol-ecules into chains along the a axis.
标题化合物[Zn(C₇H₄BrO₂)₂(C₁₀H₁₄N₂O)₂(H₂O)₂]是一种单体配合物，锌(II)原子位于对称中心上。它包含两个4-溴苯甲酸根、两个二乙烟酰胺配体和两个水分子，它们均为单齿配体。锌原子周围赤道平面上的四个氧原子形成略微扭曲的平面正方形排列，而轴向位置的两个氮原子则使扭曲的八面体几何构型得以完整。其中一个乙基的甲基在两个位置上无序分布，占有率分别约为0.65和0.35。两个芳香环的夹角为77.22 (14)°。在晶体结构中，O—H⋯O氢键将分子沿a轴连接成链。
