Bis(μ‐pyridazine‐3,6‐carboxyl­ato‐κ4N,O:N′,O′)bis­[diaqua­zinc(II)]

The title crystal structure, [Zn2(C6H2N2O4)2(H2O)4], is composed of discrete centrosymmetric mol­ecular dimers in which two ZnII 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—H⋯O hydrogen bonds [H⋯O = 2.04 (4)–2.10 (5) A]
