trans-Diaquabis(6-methoxycarbonylpyridazine-3-carboxylato-κ2N,O)zinc(II) dihydrate

Abstract

In the title centrosymmetric complex, [Zn(C7H5N2O4)2(H2O)2]·2H2O, the ZnIIion is coordinated in atransmode by two symmetry-related bis-chelating 6-methoxycarbonylpyridazine-3-carboxylate ligandsviaN and O atoms, and by two aqua ligand O atoms in axial positions, in a slightly distorted octahedral environment. In the crystal structure, complex molecules are linked by intermolecular O—H...O hydrogen bonds between coordinated and solvent water molecules and carboxylate O atoms, forming molecular ribbons propagating along theaaxis.
