COPPER(II) COMPLEXES WITH TRIMETHYL PHOSPHITE AND PERFLUORINATED CARBOXYLATES

New Cu(II) complexes with trimethyl phosphite and aliphatic perfluorin ated carboxylates of the type Cu(OH)(OOCR)[P(OCH3)(3)], where R = CF3, C2F5, C3F7, C6F13, C7F15, C9F19 were synthesized and their spectrosco pic and thermal properties studied. EPR spectra and magnetic susceptib ility results indicate the formation of polymeric complexes with five coordinated CU(II). Examination of COO absorption bands suggests bridg ing carboxylates in the coordination sphere. Hydroxy group is also in bridging position whereas trimethyl phosphite is monodentately bonded. Thermal decomposition is a multistage process, which in nitrogen and air atmosphere yields a mixture of Cu2O and Cu2P2O7.
