In the title complex, [Cu(C(7)H(4)IO(2))(2)(C(6)H(6)N(2)O)(2)(H(2)O)(2)], the Cu(II) cation is located on an inversion center and is coordinated by two monodentate 2-iodo-benzoate (IB) anions, two nicotinamide (NA) ligands and two water mol-ecules in a distorted octa-hedral coordination geometry. The dihedral angle between the carboxyl-ate group and the adjacent benzene ring is 32.12 (14)°, while the pyridine ring and the benzene ring are oriented at a dihedral angle of 82.02 (5)°. The coordinating water mol-ecule links with the carboxyl-ate group via an intra-molecular O-H⋯O hydrogen bond. In the crystal, N-H⋯O, O-H⋯O and weak C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional supra-molecular network.
在标题配合物[Cu(C₇H₄IO₂)₂(C₆H₆N₂O)₂(H₂O)₂]中，Cu(II)阳离子位于一个对称中心上，由两个单齿的2-碘苯甲酸根（IB）阴离子、两个烟酰胺（NA）配体和两个水分子以扭曲的八面体配位几何构型配位。羧酸根基团与相邻苯环之间的二面角为32.12 (14)°，而吡啶环和苯环的二面角为82.02 (5)°。配位水分子通过分子内O—H⋯O氢键与羧酸根基团相连。在晶体中，N—H⋯O、O—H⋯O和弱C—H⋯O氢键将分子连接成三维超分子网络。
