Formation of unusual ruthenium(III) carbonyl complex through ONS tricoordination of salicylaldehyde-N-phenylthiosemicarbazone

An unusual coordination mode of salicylaldehyde N-phenylthiosemicarbazone (H-2-Sal-Ptsc) ligand was observed in unusual ruthenium(Ill) carbonyl complex for the first time when it was reacted with [RuHCl(CO)(PPh3)(3)]. The EPR and electrochemical analysis conformed the formation of Ru(III) species. (c) 2006 Elsevier B.V. All rights reserved.
