The association of Eu(fod)3 (L) to adamantanone (S) in CDCI 3 was studied by 1H n.m.r. spectroscopy. From the concentration dependence of the induced shifts the bound shifts were obtained by an optimization procedure and a gradient method. The equilibrium constants for the formation of complexes LS, LS2, and LS3 were calculated. The best fit was found for the two-step association LS,LS 2 with association constants K11 63 dm3 mol-1 and K12 514 dm3 mol-1. The position of europium in the complex adduct was studied by one- and four-site binding models and both results were statistically compared.
