Heating of [RhCl3(MeCN)3] in benzyl cyanide at 100 °C gives the substitution product mer-[RhCl3(PhCH2CN)3] (90% yield), whose recrystallization from an acetone/toluene mixture leads to formation of the toluene solvate mer-[RhCl3(PhCH2CN)3]·1/2 C6H5Me. The crystal structure of the latter, determined by X-ray single-crystal diffractometry, shows an unusual self-assembly due to intermolecular CH···Cl hydrogen bonding with concomitant clathration of toluene. Diffusion of ammonia into a solution of mer-[RhCl3(PhCH2CN)3] in neat benzyl cyanide brings about a facile rhodium(III)-assisted addition of NH3 to the coordinated nitrile species to produce the amidine complex mer-[RhCl3{PhCH2C(NH2)=NH}3] (83% yield). Both starting material and the product were characterized by elemental analyses, FAB-MS, IR and 1H and 13C{1H} NMR spectroscopy. The crystal structure of mer-[RhCl3{PhCH2C(NH2)=NH}3] provides the first example of a rhodium(III) complex with a monodentate amidine ligand.
