X-Ray crystallographic determination of the infinite, helical, polymeric structure formed from acetylacetonato(trichloroacetato)copper(II) chemical units

Abstract

The infinite, left-handed, helical structure of catena-µ-trichloroacetato-acetylacetonatocopper(II) has been determined by X-ray methods: each copper atom is surrounded by six oxygen atoms; two from a bidentate acetylacetonato-ligand, two from separate trichloroacetato-ligands which bridge to neighbouring copper atoms in the spiral, and two which are atoms of ligands bidentate to these neighbouring copper atoms.
