Di-μ-methanolato-κ4O:O-bis[bis(3-methyl-5-phenyl-1H-pyrazole-κN2)(nitrato-κO)copper(II)]

Abstract

Copper nitrate in methanol solution cleaves the N—Cmethanol bond when reacted with 3-methyl-5-phenylpyrazole-1-methanol to yield the centrosymmetric dinuclear title compound, [Cu2(CH3O)2(NO3)2(C10H10N2)4], in which the CuII atom is linked to a nitrate ion, two methanolate ions and two pyrazole ligands in a distorted square-pyramidal environment. The O atom of the nitrate anion occupies the apical site. The crystal structure features intramolecular N—H...O hydrogen bonds.
