A novel one-dimensional copper(II) imino nitroxide polymer

Abstract

A copper(II) complex [Cu(im2-py)(4,4′-bipy)(NO3)](NO3)·1.5H2O (im2-py = 2-(2′-pyridyl)-4,4,5,5-tetramethylimidazoline-1-oxyl; 4,4′-bipy = 4,4′-bipyridyl) has been synthesized by reaction of Cu(NO3)·3H2O with im2py and 4,4-bipyridyl in methanol solution. Its crystal structure has been determined by X-ray diffraction. The structure shows that each copper ion is coordinated by a bidentate imino nitroxide radical, two 4,4′-bipyridyl ligands and a nitrate group to form a distorted square pyramidal environment. The crystal structure consists of chains of copper ions linked by 4,4′-bipyridyl.
