2N,O2)zinc(II)Abstract: The centrosymmetric title compound, [Zn(C14H8N2O8)2(H2O)2], shows a distorted octahedral coordination. The four donor atoms of the two coplanar 3-carboxypyridine-2-carboxylate or (2,3-pydcH)- anions form a square-planar arrangement around the ZnII centre. This crystal structure has an infinite three-dimensional framework. The stabilizing interactions existing in the crystal structure are intermolecular O-H
O and very strong intramolecular O-HO hydrogen bonds. H atoms of coordinated water molecules participate in hydrogen-bonded chains described by C22(12) and C11(8) graph-set descriptors.
