The title compound, [Zn(C(7)H(3)NO(4))(C(6)H(6)N(4)S(2))(H(2)O)]·4H(2)O, assumes a distorted octa-hedral coordination geometry around the Zn(2+) cation, formed by a diamino-bithia-zole (DABT) mol-ecule, a pyridine-2,6-dicarboxyl-ate anion and a water mol-ecule. The pyridine-2,6-dicarboxyl-ate anion chelates to the Zn(II) atom with a facial configuration. Within the chelating DABT ligand, the two thia-zole rings are twisted by a dihedral angle of 14.52 (8)° with respect to each other. O-H⋯O and N-H⋯O hydrogen bonds occur in the crystal structure.
标题化合物[Zn(C₇H₃NO₄)(C₆H₆N₄S₂)(H₂O)]·4H₂O中，Zn²⁺阳离子周围呈现扭曲的八面体配位几何构型，由一个二氨基联噻唑（DABT）分子、一个吡啶 - 2,6 - 二羧酸根阴离子和一个水分子构成。吡啶 - 2,6 - 二羧酸根阴离子以面式构型与Zn(II)原子螯合。在螯合的DABT配体中，两个噻唑环相对于彼此扭转的二面角为14.52 (8)°。晶体结构中存在O - H⋯O和N - H⋯O氢键。
