trans-Diaquabis(6-methoxycarbonylpyridazine-3-carboxylato-²N,O)zinc(II) dihydrate

W. Starosta and J. Leciejewicz

Abstract: In the title centrosymmetric complex, [Zn(C₇H₅N₂O₄)₂(H₂O)₂]·2H₂O, the Zn^II ion is coordinated in a trans mode by two symmetry-related bis-chelating 6-methoxycarbonylpyridazine-3-carboxylate ligands via N 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-HO hydrogen bonds between coordinated and solvent water molecules and carboxylate O atoms, forming molecular ribbons propagating along the a axis.
