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.
