Abstract:
The reaction of the carbodiphosphorane C(PPh 3 ) 2 (1) with [Co 2 (CO) 8 ] results in the formation of the salt-like complex (HC{PPh 3 } 2 )[Co(CO) 4 ] (2) in high yield if THF is used as the solvent. The proton of the cation stems from THF degradation. When the reaction is carried out in toluene, the tetranuclear cluster [Co 4 (CO) 10 (PPh 3 )(μ 4 -CCPPh 3 )] (3) is formed in low yield as the only complex which could be identified by X-ray analysis. The solvate 3 ·C 7 H 8 crystallizes in the triclinic space group P1̄ with a = 1040.8(2), b = 1387.4(2), c = 1923.0(2) pm, α = 71.96(1)°, β = 88.69(1)°, γ = 71.46(1)°, Z = 2. The structure of the cluster with 64 CVE is that of a “spiked triangle” in which the triphenylphosphonioacetylide CCPPh 3 acts as a six-electron donor and the bonding mode is that of a μ 4 -η 2 coordination.
