The polynucleating bridging ligands L¹ and H3L² were simply prepared via a Heck coupling of 4-vinylpyridine or 4-methoxystyrene with 1,3,5-tribromobenzene; in the trinuclear complexes of L¹ and L² with a paramagnetic Cl> moiety at each binding site the EPR spectra demonstrate that all three unpaired electrons are in 'fast exchange' between all three metal centres.
