The novel NCO chelating ligand L, 1-CH2N(CH3)2-3-CH2OCH3-C6H4, was prepared in four steps from commercially available m-tolunitrile in a good yield. Successful lithiation of this ligand was achieved by the reaction with n-BuLi in hexane. Using of this in situ prepared organolithium compound LLi in the reactions with MCl3 (M = Sb, Bi) in 1:1 molar ratio led to isolation of the desired mono-organocompounds MLCl2 (M = Sb (1), Bi (2)). Their structures were studied both in solution (NMR) and in the solid state (X-ray diffraction), and were compared with those of the NCN- and OCO-chelating analogues.
