Abstract

Variable temperature ^p13C-n.m.r. spectra of CO₄(CO)₁₂ in viscous solution show that in solid state structure is maintained in solution and that total scrambling of the COs occurs. Variable temperature ¹³C-n.m.r. spectra of HFeCo₃(CO)₁₂, isostructural with Co₄(CO)₁₂, show that this molecule is stereochemically non rigid only in the Co₃ unit. In the derivatives in which one or more COs are substituted with a group V ligand the cobalt bonded carbonyls are rigid. The substitution occurs by stepwise replacement of one carbonyl group on each of the cobalt atoms.
