In the title compound, [Cd(C(10)H(9)N(4)O(2)S)(2)(C(3)H(7)NO)(2)(H(2)O)]·H(2)O, the Cd(II) ion displays a grossly distorted octa-hedral (or irregular) mer-CdN(3)O(3) coodination polyhdron arising from its coordination by one N,N'-bidentate sulfadiazinate anion, one monodentate sulfadiazinate anion, two O-bonded dimethyl-formamide molecules and one water mol-ecule. A short Cd⋯N contact [2.890 (3) Å] to the monodentate sulfadiazinate ion also occurs. The dihedral angles between the planes of the aromatic rings of the anions are 86.81 (14) and 68.65 (14)°. The crystal structure features inter-molecular N-H⋯O, O-H⋯O and O-H⋯N hydrogen bonds.
在标题化合物[Cd(C₁₀H₉N₄O₂S)₂(C₃H₇NO)₂(H₂O)]·H₂O中，Cd(II)离子呈现出严重扭曲的八面体（或不规则）面式CdN₃O₃配位多面体，这是由于它与一个N,N'-双齿磺胺嘧啶阴离子、一个单齿磺胺嘧啶阴离子、两个通过O键合的二甲基甲酰胺分子以及一个水分子配位所致。还存在Cd与单齿磺胺嘧啶离子的短接触[2.890 (3) Å]。阴离子芳香环平面之间的二面角为86.81 (14)°和68.65 (14)°。晶体结构具有分子间N - H⋯O、O - H⋯O和O - H⋯N氢键。
