Chlorobis[2-(2-pyridyl)ethanol]copper(II) chloride

S. Hamamci, V. T. Yilmaz and C. Thöne

Abstract: The structure of the title complex, [CuCl(pyet)₂]Cl [pyet is 2-(2-pyridyl)ethanol, C₇H₉NO], consists of a chloride anion and a [Cu(Cl)(pyet)₂]⁺ cation. In the cation, the copper(II) ion possesses a square-pyramidal coordination geometry, with a chloro and two neutral pyet ligands. Each pyet ligand acts as an N,O-bidentate ligand and forms a six-membered chelate ring around the copper(II) ion. The H atoms of the hydroxy groups of the pyet ligands form strong hydrogen bonds with chloride ions, while the phenyl and ethylene H atoms of pyet are involved in weak interactions with both the chloro ligand and chloride ion.
