Tetra-aqua-bis-[2-(pyridin-4-yl-?N)pyrimidine-5-carboxyl-ato]zinc.

ABSTRACT: In the title complex, [Zn(C(10)H(6)N(3)O(2))(2)(H(2)O)(4)], the Zn(II) ion lies on an inversion center and is coordinated in a slightly distorted octa-hedral geometry by two N atoms from two 2-(pyridin-4-yl)pyrimidine-5-carboxyl-ate ligands and four water mol-ecules. In the symmetry-unique part of the mol-ecule, the pyridine and pyrimidine rings form a dihedral angle of 7.0?(1)°. In the crystal, the coordinating water mol-ecules act as donor groups and carboxyl-ate O atoms act as acceptors in O-H?O hydrogen bonds, forming a three-dimensional network.
