Bis{2,6-bis[1-(4-fluorophenylimino)ethyl]pyridine}-1κ3N,N′,N′′;3κ3N,N′,N′′-di-μ-chlorido-1:2κ2Cl:Cl;2:3κ2Cl:Cl-trichlorido-1κCl,2κCl,3κCl-2-copper(I)-1,3-dicopper(II)

Abstract

The title complex, [Cu3Cl5(C21H17N3F2)2], is the first reported copper trimer including both Cu(I) and Cu(II) ions. The two Cu(II) ions are five-coordinate in a significantly distorted square-pyramidal arrangement, with the bridging Cl atom located in the apical position, and the pyridine (py) N atom, the two imine N atoms and the other Cl atom located in the basal plane. The Cu(I) ion is in a trigonal planar configuration surrounded by three Cl atoms. The structure is stabilized by intra- and intermolecular C-H...Cl and C-H...pi(py) hydrogen bonds.
