In the title compound, [Zn(C6H4NO2)2(H2O)2]·0.5C3H7NO, the Zn II ion is coordinated in a distorted octahedral N2O4 environment by two N,O-chelating pyridine-2-carboxylate ligands and two cis water molecules. The chelating pyridine-2-carboxylate ligands create two five-membered Zn/N/C/C/O rings, which form a dihedral angle of 86.4 (2)°. In the crystal, O - H⋯O hydrogen bonds link the complex molecules into a two-dimensional network parallel to (100). The dimethylformamide solvent molecule is disordered about a twofold rotation axis. |
