摘要：
The diamagnetic osmium(IV) complexes [Os(SR)4(PR'3)] (R = C6F5, C6F4H-4, C6H4F-4, or Ph, R' = Ph; R = C6F5 or C6F4H-4, R'3, = Me2Ph) and [OsCl(SC6F5)2(SC6H4X-3)(PMe2Ph)] (X = F or CF3) have been prepared. The complex [Os(SC6F4H-4)4(PPh3)] has an essentially trigonal-bipyramidal structure with an apical PPh3 group [Os-P 2.391 (5), Os-S(ap) 2.414(5), mean Os-S(eq), 2.207(7) angstrom]. The structure of [OsCl(SC6F5)2(SC6H4CF3-3)(PMe2Ph)] is a somewhat distorted triagonal bipyramid with apical Cl- and PMe2Ph groups [Os-Cl 2.420(2), Os-P 2.340(2), mean Os-SC6F5 2.206(2), Os-SC6H4CF3 2.187(2) angstrom]. The spectroscopic properties of these compounds are reported and the possibility of isomerism in solution is discussed.
