In the title compound, [Cd(C(8)H(4)O(5))(C(12)H(12)N(2))], the Cd(II) cation is coordinated by three 5-hy-droxy-isophthalate anions and one 5,5'-bimethyl-2,2'-bipyridine ligand in a distorted CdO(4)N(2) octa-hedral geometry. The 5-hy-droxy-isophthalate anions bridge the Cd cations, forming a two-dimensional polymeric complex parallel to (100). In the complex, the hy-droxy group is linked to the uncoordinated carb-oxy-O atom via an O-H⋯O hydrogen bond. Weak C-H⋯O hydrogen bonds are also present in the crystal structure. One of the methyl groups is disordered over two positions in a 0.536 (11):0.464 (11) ratio.
在标题化合物[Cd(C₈H₄O₅)(C₁₂H₁₂N₂)]中,Cd(II)阳离子由三个5-羟基间苯二甲酸根阴离子和一个5,5'-二甲基-2,2'-联吡啶配体配位,形成扭曲的CdO₄N₂八面体几何构型。5-羟基间苯二甲酸根阴离子桥连Cd阳离子,形成平行于(100)的二维聚合物配合物。在配合物中,羟基通过O—H⋯O氢键与未配位的羧基O原子相连。晶体结构中还存在弱的C—H⋯O氢键。其中一个甲基在两个位置上无序排列,比例为0.536 (11):0.464 (11)。
