Triphenylphosphine oxide adducts of copper(II) dichloro‐, trichloro‐ and trifluoroacetate were prepared. Electronic, IR and EPR spectra as well as magnetic data over the temperature range 81–301 K have been mainly used for the determination of the stereochemistry and electronic structure of the adducts. The spectral and magnetic behaviours of the adducts are similar to that of copper(II) acetate hydrate. Some correlations between the magnetic and spectral data as well as the acidity of the respective acids are discussed. Cu(F 3 CCOO) 2 Ph 3 PO, represent the first example of a stable binuclear copper(II) trifluoroacetate adduct.
