Bis(3-aminopyridine-κN)(4,4′-dimethyl-2,2′-bipyridine-κ2N,N′)(perchlorato-κO)copper(II) perchlorate

Abstract

The title compound, [Cu(ClO 4 )(C 5 H 6 N 2 ) 2 (C 12 H 12 N 2 )]ClO 4 , was prepared by in situ partial ligand substitution between 3-aminopyridine and 4,4'-dimethyl-2,2'-bipyridine at room temperature. The central copper(II) ion is five-coordinated by one bidentate 4,4'-dimethyl-2,2'-bipyridine molecule, two monodentate pyridine-coordinated 3-aminopyridine molecules and one apical O atom from the perchlorate counterion. Intermolecular N-H···O and C-H···O hydrogen-bonding interactions form a hydrogen-bond-sustained network.
