Abstract
The complete analysis of the H-1 NMR spectra of [(C(5)Me(5))Ir(glycina te)Cl] and [(C(5)Me(5))Ir(N-methyl-glycinate)Cl] provide information f or the conformational analysis of the five-membered N-C-C-O-Ir ring. A Karplus relationship has been established for these metallacycles [(3 )J(H,H) = 8.9 cos phi - 1.0 cos phi + 0.81].
