摘要:
                                The reactions of ReOCl3(Me2S)(OPPh3) with monodentate P(OMe)(3) (P) and bidentate (OCMe2CMe2O)POCMe2CMe2OP(OCMe2CMe2O), (P-P) phosphites afford fac-ReOCl3P2 (I) and fac-ReOCl3(P-P) (2) respectively. Both blue-violet 1 and 2 have been characterized by NMR, IR and UV-Vis spectroscopies as well as by X-ray crystallography. Crystal data of ReOCl3P2 (1): crystal class triclinic, space group P (1) over bar (No 2), a= 8.558(2), b = 8.921(2), c= 12.617(3) Angstrom; alpha = 74.42(3), beta= 81.81(3), gamma= 63.43(1)degrees; V=829.6(3)Angstrom(3), Z=2. Crystal data of ReOCl3(P-P) (2). monoclinic, space group P2(1/n), (P2(1/c) No 14), a=9.615(2), b=16.424(3), c= 17.395(3) Angstrom; beta= 99.81(3); V=2706.8(9)Angstrom(3), Z=4. There is 72:28 orientational disorder in 2 between the mutually trans-oxo and chloride ligands. In both I and 2, the rhenium atoms are six coordinate with triply bonded terminal oxo ligands (1 Re-O =1.654(4) Angstrom), (2 Re-O = 1.692(15) Angstrom) and chlorides in facial arrangements.
