The photo-induced substitution of a CO ligand has been used to prepare the halfsandwich complexes (η 3 -C 3 H 5 )V(CO) 4 [P(C 7 H 7 ) 3 ] (1), (η 5 -C 5 H 5 )V(CO) 3 [P(C 7 H 7 ) 3 ] (2), (η 7 -C 7 H 7 )V(CO) 2 [P(C 7 H 7 ) 3 ] ( 3), (η 6 -C 6 H 3 Me 3 )Cr(CO) 2 [P(C 7 H 7 ) 3 ] (4), and (η 5 -C 5 H
The olefinic phosphane P(C 7 H 7 ) 3 (5) behaves as a tetradentate tripod ligand in [RhCl{P(g 2 -C 7 H 7 ) 3 }] (6), using all 3 cyclohepta-2,4,6-trienyl substituents as g 2 -coordinating side-arms. Nucleophilic displacement of the one-electron chloro ligand by halides or pseudohalides to give [RhX{
Stepwise introduction of the potential tripod ligands tris(3,5-dimethyl-1-pyrazolyl)borate (Tp\*) and tris(1cyclohepta-2,4,6-trienyl)phosphane into the coordination sphere of rhodium(I) leads mainly to [Tp\*Rh{P(C 7 H 7 ) 3 }] (4), in which Tp\* is linked to the rhodium through a single pyrazolyl gr
