Abstract: [Ru-II(por)(PHnPh3-n)(2)], [Os-II(por)(CO)(PHnPh3-n)] (n=1, 2), and [Os-II(F-20-tpp){P(OH)Ph-2}(PHPh2)] (F-20-tpp = 5,10,15,20-tetrakis(pentafluorophenyl)porphyrinato dianion) were prepared from the reaction of [M-II(por)(CO)] (M=Ru, Os) or [Os-VI(por)O-2] with the respective primary/ secondary phosphane and characterized by H-1 NMR, P-31 NMR, UV/Vis, and IR spectroscopy, mass spectrometry, and elemental analysis. The reaction of [Os-VI(por)O-2] with PHPh2 also gave minor amounts of [Os-II(por)-{P(OH)Ph-2}(2)]. [Ru-II(F-20-tpp)(PH2Ph)(2)] exhibits a remarkable stability toward air and shows a reversible metal-centered oxidation couple at E-1/2=0.39V versus [Cp2Fe](+/0) in the cyclic voltammogram. The structures of [Ru-II(F-20-tpp)(PH2Ph)(2)]9 center dot 2CH(2)Cl(2), [Ru-II(4-Cl-tpp)(PHPh2)(2)]center dot 2 CH2Cl2 (4-Cl-tpp 5,10,15,20-tetrakis(p-chlorophenyl)porphyrinato dianion), [Ru-II(F-20-tpp)(PHPh2)(2)], and [Os-II(F-20-tpp){P(OH)Ph-2}(2)] were determined by X-ray crystallography and feature RuP distances of 2.3397(11)-2.3609(9) angstrom and an Os-P distance of 2.369(2) angstrom.
