M. Gryz, W. Starosta and J. Leciejewicz

Abstract: The title crystal structure, [Zn₂(C₆H₂N₂O₄)₂(H₂O)₄], is composed of discrete centrosymmetric molecular dimers in which two Zn^II atoms are coordinated by two fully deprotonated pyridazine-3,6-dicarboxylate ligands via N,O-bonding and two water O atoms in axial positions forming slightly distorted octahedral environments. In the crystal structure, a three-dimensional network is formed via intermolecular O-HO hydrogen bonds [HO = 2.04 (4)-2.10 (5) Å]
