STRUCTURAL AND VIBRATIONAL PROPERTIES OF DICHLOROBIS(TRIPHENYLPHOSPHINEOXIDE)COPPER(II)

Dichlorobis(triphenylphosphineoxide)copper(II) has been prepared as a side product and a subunit of tetranuclear mu(4)-oxo bridged complexes . The molecular structure, already known in the literature, was redete rmined using X-ray diffraction and slight differences are discussed. T he far IR spectra were recorded and assigned. Structural features of t he distorted tetrahedral coordination sphere of copper(II) have been e lucidated by performing a vibrational analysis based on quantumchemica l calculations using DFT methods.
