Abstract: The preparation and some properties of Cu(OPPh3)4X2 -2H2O (OPPh3 = triphenylphosphine oxide; X = Cl, Br) complexes are described. Thermal properties of these complexes as well as their infrared, electronic, e.p.r. spectra and magnetic properties were studied. Obtained results indicate that the Cu(OPPh3)4Cl2-2H2O complex contains chromophore [Cu04Cl2] with oxygen atoms in equatorial positions and chlorine atoms in axial positions of distorted tetragonal bipyramide. In Cu(OPPh3)4Br2 -2H2O we assume that oxygen atoms of triphenylphosphine oxide are shifted from equatorial plane with indication of a distorted tetrahedron. Water in both complexes is bonded by hydrogen bonds.
