The title Mn(II) complex, [Mn(C(7)H(4)BrO(2))(2)(C(10)H(14)N(2)O)(2)(H(2)O)(2)], is centrosymmetric. The mol-ecule contains two 2-bromo-benzoate (BB) and two diethyl-nicotinamide (DENA) ligands and two water mol-ecules, all ligands being monodentate. The four O atoms in the equatorial plane around the Mn atom form a slightly distorted square-planar arrangement, while the distorted octa-hedral coordination is completed by the two N atoms of the DENA ligands in the axial positions. The dihedral angle between the carboxyl group and the adjacent benzene ring is 79.95 (11)°, while the pyridine and benzene rings are oriented at a dihedral angle of 45.66 (6)°. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into infinite chains.
标题为Mn(II)配合物[Mn(C₇H₄BrO₂)₂(C₁₀H₁₄N₂O)₂(H₂O)₂]，具有中心对称性。该分子包含两个2 - 溴苯甲酸酯（BB）和两个二乙基烟酰胺（DENA）配体以及两个水分子，所有配体均为单齿配体。围绕Mn原子的赤道平面上的四个O原子形成略微扭曲的平面正方形排列，而轴向位置的DENA配体的两个N原子则完成了扭曲的八面体配位。羧基与相邻苯环之间的二面角为79.95 (11)°，而吡啶环和苯环的二面角为45.66 (6)°。在晶体结构中，分子间的O - H⋯O氢键将分子连接成无限链。
