Aqua[2-(5-ethyl-2-pyridyl-κN)-4-isopropyl-4-methyl-5-oxo-4,5-dihydroxyimidazol-1-ido-κN1](5-methyl-1H-pyrazole-3-carboxylato-κ2N2,O)copper(II) 1.33-hydrate

Abstract

In the title complex, [Cu(C5H5N2O2)(C14H18N3O)(H2O)]·1.33H2O, the CuII ion is coordinated in a slightly distorted square-pyramidal environment. The basal plane is formed by two N atoms from a 2-(5-ethyl-2-pyridyl-κN)-4-isopropyl-4-methyl-5-oxo-4,5-dihydroxyimidazol-1-ide ligand and by one O atom and one N atom from a 5-methyl-1H-pyrazole-3-carboxylate ligand. The apical position is occupied by a water molecule. In the crystal structure, O—H...O, O—H...N and N—H...O hydrogen bonds lead to a three-dimensional supramolecular network.
