Abstract
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 {Mo(NO){BH(C3HN2Me2-3,5)3}Cl} moiety [BH(C3HN2Me2-3,5)3= tris(3,5-dimethylpyrazol-1-yl) hydroborate] at each binding site the EPR spectra demonstrate that all three unpaired electrons are in ‘fast exchange’ between all three metal centresKeywords
