N,N′,N″-Triphenylguanidinate(1–) complexes of ruthenium and palladium: syntheses and crystal structures†
Abstract
N,N′,N″ -Triphenylguanidine (HTpg) reacted with [Ru(O2CCF3)2(CO)(PPh3)2] in boiling toluene to yield [Ru(Tpg)2(CO)(PPh3)], the first example of a mononuclear complex containing two chelate guanidinate(1–) ligands. Palladium(II) acetate reacted with HTpg in warm benzene to form an adduct [Pd(O2CMe)2(HTpg)2] which, under more forcing conditions, converts into the novel binuclear guanidinate(1–) bridged complex [{Pd(µ-Tpg)(Tpg)}2]. Crystal structures have been determined for both guanidinate(1–) complexes.
