The X-ray crystal structure of the elusive isomer of Os3(CO)10(PPh3)2 in which the two phosphine ligands are cis and trans with respect to the phosphine-substituted Os-Os edge has been determined; the first dire

Electrophilic attack on the bridging phosphido moiety of (1) allows the formation of new phosphorus-containing compounds.The phosphido clusters (R = (CH2)6I (2a), (CH2)10I (2b), C4H8OH (2c), HOs3(CO)10(PPh3) (4a), HOs3(CO)10 (4b) have been synthesized by the reaction of 1 with the appropriate electrophiles.When R = alkyl, both exo- and endo-isomers are formed.The formation of both isomers indicates that endo-attack plays a significant role in these reactions.When R = (μ-H)Os3(CO)10(PR3) the exo-isomers are the exclusive products.Reaction of the ruthenium analogue of 1 with leads to the formation of 4-P)> (6).The crystal structure of (μ3-PH)> (4b) is presented.Key words: Phosphido moiety, cluster, Osmium, Ruthenium, electrophilic attack, isomer.

X-ray crystal structures of six complexes M3(CO)11(L) (M = Ru, L = PPh(OMe)2, P(OCH2CF3)3, P(OCH2)3CEt and AsPh3; M = Os, L = PPh3 and PPh(OMe)2) have been determined.Consideration of these results, together with other published data, allowed several conclusions to be drawn concerning the effect of substituting one CO group in M3(CO)12 (M = Ru, Os) by a P- or As-donor ligand.The most important are that L occupies an equatorial site, the M-M separation cis to L increases with increasing cone angle of L, while the COeq ligand cis to L on the same metal atom is more tightly bound.Distortions of the M3L12 molecule from D3h to D3 geometry appear to be related to the ?-donor properties of L.The reactions between Ru3(CO)12 and P(OCH2CF3)3, and between Os3(CO)12 and PPh3 or PPh(OMe)2, to give M3(CO)12-n(L)n (n = 1-3), are described.Crystal data: Ru3(CO)11, monoclinic, P21/c, a 9.647(3), b 20.529(7), c 14.692(5) Angstroem, β 119.93(2) deg, U 2522(1) Angstroem3, Z = 4, N0 (observed data, with I>3?(I)) = 5829, R = 0.035, R' = 0.037; Ru3(CO)11, triclinic, P1, a 12.920(1), b 11.530(2), c 10.189(1) Angstroem, α 85.93(1), β 86.57(1), γ 70.66(1) deg, U 1427(1) Angstroem3, Z = 2, N0 = 4061, R = 0.038, R' = 0.054; Ru3(CO)11, monoclinic, P21/c, a 13.57(1), b 14.779(1), c 12.362(3) Angstroem, β 98.34(4) deg, U 2453(1) Angstroem3, Z = 4, No= 5950, R = 0.039, R' = 0.054; Ru3(CO)11(AsPh3), monoclinic, C2/c, a 22.496(6), b 16.348(4), c 17.345(5) Angstroem, β 103.65(2) deg, U 6198(3) Angstroem3, Z = 8, No= 6071, R = 0.032, R' = 0.028; Os3(CO011(PPh3), monoclinic, C2/c, a 22.196(5), b 16.265(3), c 17.370(5) Angstroem, β 103.86(2) deg, U 6088(33) Angstroem3, Z = 8, No= 4125, R = 0.031, R' = 0.033; Os3(CO)11, monoclinic, P21/c, a 10.817(3), b 14.993(4), c 16.174(3) Angstroem, β 101.87(2) deg, U 2567(1) Angstroem, Z = 4, No = 5506, R = 0.047, R' = 0.057.
