Diaqua-trans-bis(pyridazine-3-carboxylato-κ2O,N)zinc(II)
2004
In the structure of the title compound, [Zn(C5H3N2O2)2(H2O)2], the ZnII ion is located on a centre of symmetry. The coordination around the ZnII atom is slightly distorted octahedral, with two equatorial pyridazine-3-carboxylate ligands in a trans arrangement. A pyridazine-ring N atom [Zn—N = 2.0742 (15) A] and one carboxylate O atom [Zn1—O2 = 2.0744 (14) A] from each ligand coordinate to the metal. Two water O atoms [Zn—O = 2.1934 (17) A] are coordinated in axial positions. The coordinated water molecules act as hydrogen-bond donors to the unbonded carboxylate O atoms in adjacent monomers, forming a three-dimensional network.
