title: Aqua-bis(5-methyl-pyrazine-2-carboxyl-ato)zinc(II) trihydrate.
abstract: In the title compound, [Zn(C(6)H(5)N(2)O(2))(2)(H(2)O)]·3H(2)O, the Zn(II) centre is five-coordinated by two O,N-bidentate Schiff base ligands and one O atom from a water mol-ecule in a slightly distorted square-pyramidal geometry. In the crystal, the complex and uncoordinated water mol-ecules are linked by O-H⋯O, O-H⋯N and C-H⋯O hydrogen bonds, forming a three-dimensional network.
