title: Aqua-[2-(5-ethyl-2-pyridyl-κN)-4-iso-propyl-4-methyl-5-oxo-4,5-dihydroxy-imidazol-1-ido-κN](5-methyl-1H-pyrazole-3-carboxyl-ato-κN,O)copper(II) 1.33-hydrate.
abstract: In the title complex, [Cu(C(5)H(5)N(2)O(2))(C(14)H(18)N(3)O)(H(2)O)]·1.33H(2)O, the Cu(II) 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-dihydroxy-imidazol-1-ide ligand and by one O atom and one N atom from a 5-methyl-1H-pyrazole-3-carboxyl-ate ligand. The apical position is occupied by a water mol-ecule. In the crystal structure, O-H⋯O, O-H⋯N and N-H⋯O hydrogen bonds lead to a three-dimensional supra-molecular network.
