Synthesis and crystal structure of a 4,4’-bipyridine linked dinuclear copper(II) complex derived from 2-{[2-(2-hydroxyethylamino)ethylimino]methyl}-6-methylphenol

A novel 4,4'-bipyridine linked dinuclear copper(II) complex, [Cu2L2(bipy)](NO3)2·bipy (L = 2-{[2-(2-hydroxyethylamino)ethylimino]methyl}-6-methylphenol; bipy = 4,4'-bipyridine), was prepared and characterized by elemental analyses, IR spectroscopy, and single-crystal X-ray diffraction. The Cu∙∙∙Cu distance is 11.129(2) Å. The CuII atom is coordinated by one phenolate O, one imine N, and one amine N atoms of a Schiff base ligand, and one N atom of the bridging 4,4'-bipyridine ligand, forming a square planar geometry. In the crystal structure of the complex, the dinuclear copper complex cations are linked by 4,4'-bipyridine molecules through intermolecular O–H···N hydrogen bonds, to form 1D chains running in the [2 0 –1] direction.
