Crystal structure of dinuclear azide-bridged copper(II) complex [Cu2((3,4-MeO-Ba)2En)2(μ1,1-N3)2(N3)2]{(3,4-MeO-Ba)2En=N,N′-Bis(3,4-dimethoxybenzylidene)-1,2-ethanediamine}

New dinuclear copper(II)-azido complex [Cu2((3,4-MeO-Ba)2En)2(μ1,1-N3)2(N3)2] (I) ((3,4-MeO-Ba)2En = N,N′-bis(3,4-dimethoxybenzylidene)-1,2-diaminoethane) has been synthesized and characterized by elemental analyses, FT-IR spectroscopy, and X-ray single-crystal diffraction. Complex I consists of a dinuclear unit that represents a new example of a copper(II)-azido compound and the Cu2+ ions are bridged by two azido ions in a double end-on fashion, consisting of two terminally bonded azido ligands. The Schiff base ligand (3,4-MeO-Ba)2En is chelated by two imino nitrogen atoms.
