The synthesis and characterisation by H-1, C-13 and Co-59 NMR spectroscopy (the latter only for cation A), single-crystal X-ray crystallography and FAB mass spectrometry of two closely related pendent-arm macrocyclic complexes of cobalt(III) and rhodium(III), containing pendent metal-carbon bonds, are reported and compared {the tetraphenylborate salt of the six-coordinate [mono(acetone)(5,16-dihydro-16-(exo-norbornane-2,3-diyl-kappa C-2)-6,8,15,17-tetramethyldibenzo[b,i][1,4,8,11]-tetraazadecinato-kappa(4)N(5,9,14,18))cobalt(III)] (cation A), and the hexafluorophosphate salt of the five-coordinate [5,16-dihydro-16-(exo-norbornane-2,3-diyl-kappa C-2)6,8,15,17-tetramethyldibenzo[b,i]-[1,4,8,11]tetraazadecinato-kappa(4)N(5,9,?(14,18))rhodium(III)] (cation B)}. The scalar one-bond coupling constants between the metal nucleus and the coordinating carbon atom are (1)J(Rh-C)=30.4Hz and (1)J(Co-C)=117 +/- 5Hz, the latter determined from the linewidths of the C-13 and Co-59 resonances.
