Abstract: The data obtained by the study of the decomposition of the complexes Cu(OPPh₃)₄X₂ . 2H₂O(X = C1, Br) are presented. The possible transformations of the complex­es formed by decomposition were studied under different reaction conditions. Different dehydration procedures applied to Cu(OPPh₃)₄X₂-2H₂O result in the splitting off of OPPh₃ to yield the Cu(OPPh₃)₂X₂ complexes. By thermal dehydration without vacuum Cu(OPPh₃)₂Cl₂ arises in addition to Cu₄OCl₆(OPPh₃)₄. Besides, the preparation of a new orange isomer Сu(ОРРh₃)₂Сl₂ is also described.
