Abstract

High-field ¹³C NMR studies at various temperatures on ¹³C enriched samples of Co₄(CO)₁₂ and mono substituted derivatives, together with new ⁵⁹Co results can be interpreted in terms of CO exchange and ¹³C relaxation of the second kind caused by ¹³C⁵⁹Co coupling. Erstwhile missing ¹³C lines have now been observed and the details of the effects of relaxation used to assign these lines to apical CO ligands in a C_3ν structure.
