Ruthenium(II) complexes with 2-(benzylimino-methyl)-4-R-phenol containing the trans(PPh3),cis(CO,Cl)-{Ru(PPh3)2(CO)Cl}+ unit

Ru(II) complexes trans(PPh3),cis(CO,Cl)-[Ru(RL)(PPh3)2(CO)Cl] (HRL, 2-(benzylimino-methyl)-4-R-phenol (R = H, Cl, Br and OMe)) are reported. The complexes display a metal centred oxidation. X-ray structures reveal an intramolecular C-H⋯π interaction between the ortho-C-H of the benzyl group phenyl ring of RL− and a phenyl ring of PPh3.
