In the title complex, [ZnCl(2)(C(8)H(7)N(3)O(2))(2)], the Zn(II) atom is coordinated by two chloride ions and two N atoms in a distorted tetra-hedral coordination environment. In the crystal structure, mol-ecules are linked by inter-molecular C-H⋯O and O-H⋯O hydrogen bonds, forming a three-dimensional network.
