Treatment of [Cu(pcho) 2 (NCMe)][BF 4 ] 1 (pcho = 2‐(diphenylphosphino)benzaldehyde) with aqueous H 2 O 2 in THF solvent affords [Cu 2 (dpb) 2 (THF) 2 (H 2 O) 2 ] [BF 4 ] 2 2 (dpb = 2‐(diphenylphosphinoxide)‐benzoate) after crystallization from diethyl ether. This reaction involves oxidation of Cu(I) to Cu(II) ion, phosphine to phosphinoxide, and benzaldehyde to benzoate species. The crystal structure of 2 consists of two copper(II) atoms bridged by two carboxylate moieties of the dpb ligands. The coordination about each copper(II) atom is a distorted trigonal bipyramid.
