In radical-ion initiated reaction, Ru3(CO)12 reacts with 2-Ph2PC6H4CH=CH2(sp) to give Ru3(CO)10(sp) (1), containing the olefinic tertiary phosphine bridging two metal atoms.Gentle heating converts this complex to H2Ru3(μ3-HCCC6H4PPh2)(CO)8 (2), containing an acetylenic tertiary phosphine bridging all three metal atoms.Complex 1 is triclinic, space group P<*>1, a 9.336(3), b 12.598(4), c 13.781(5) Angstroem, α 77.61(3),β 85.01(3), γ 79.10(3) deg, Z = 2; complex 2 is also triclinic, space group P<*>1, a 11.653(6), b 16.284(6), c 17.284(8) Angstroem, α 66.29(3), β82.27(4), γ 88.86(4) deg, Z = 4.The structures were refined to R = 0.056, R_w = 0.059 for 1984 data and to R = 0.036, R_w = 0.041 for 4293 data .
