The thermal reaction of [Co2{μ-PPh2HCHC(O)CHCHPPh2)(CO)4] (2) with two-electron donor ligands, L, leads to the mono-and bis-substituted complexes [Co2(μ-PPh2CHCHC(O)CHCHPPh2}(CO) 3(L)] (L = PPhMe2 (3a), PPh2H (3b), P(OMe)3 (3c), CN'Bu (3d)) and [Co2{μ,-PPh2HCHC(O)CHCHPPh2}(CO) 2(L)2 (L = PPhMe2 (4a), PPh2H (4b), P(OMe)3 (4c), CN'Bu (4d)), in which CO groups rather than bound alkenes have been displaced from the metal centres. Single crystal X-ray diffraction has been used to determine the structure of [Co2(μ-PPh2CHCHC(O)CHCHPPh2}(CO)2(PPhMe2)2] -0.25[C6H14] (4a) (which crystallises in the monoclinic space group P2,/c with a = 15.932(2),b= 12.608(4),c = 23.847(3) A?, β= 98.87(3)°,Z=4). 1998 Elsevier Science S.A.
