Abstract

Five new rhenium(III) complexes of the general formula ReCl2(RFCOCHCORF)(PPh3)(OPPh3), where RF = CF3 (I), C2F5 (II), C3F7 (III), C4F9 (IV), and CF3CFOC3F7 (V), were synthesized. The known rhenium(V) complex ReOCl2(OC2H5)(PPh3)2, which can readily be obtained from metallic rhenium, was used as a precursor. Two polymorphous modifications of compound I were found and studied by X-ray diffraction analysis. The thermal properties of the synthesized complexes were characterized by the DTA-TG method.
