[cu(H2dped)](BF4)2 (H2dped = N,N?-bis(2-(diphenylphosphino)phenyl)ethane-1,2-diamine): A stable phosphine complex of copper(II)

Controlled potential oxidation of [Cu(H2dped)]1+ 1 in 1,2-dichloroethane or reaction of [Cu(H2O)6](BF 4)2 with H2dped in acetone affords the complex [Cu(H2dped)]2+ 2 i.e. a CuII species stabilized by a soft-hard (P2N2) ligand set.
