L. Carlton et al., STABILITY ENHANCEMENT OF HEAVY-METAL-MACROCYCLE COMPLEXES VIA PENDANTAMIDE COORDINATION, Journal of the Chemical Society, Chemical Communications, (8), 1994, pp. 1007-1008
Formation of the pendant-arm macrocyclic ligand is(carbamoylmethyl)-1,
4,7,10-tetraazacyclododecane L and subsequent generation of its cadmiu
m(ir) complex indicates very significant stabilisation of the complex,
compared to that observed for related macrocyclic cadmium(ri) complex
es, which either lack pendant donors altogether, or have other types o
f neutral oxygen donors attached to the macrocycle, and compared to co
mplexes of L with lighter metal ions.
