Synthesis, Spectroscopic and Molecular Studies of Half‐Sandwich η6‐Arene Ruthenium, Cp* Rhodium and Cp* Iridium Metal Complexes with Bidentate Ligands

Abstract The bidentate ligand benzoyl(2‐pyridyl)thiourea ( L1 ) was prepared by reaction of benzoyl isothiocyanate with primary amine (2‐aminopyridine) but the reaction with secondary amine bis(2‐pyridyl)amine, yielded the unexpected product bis(2‐pyridyl)benzoylamine ( L2 ). Mononuclear complexes of the general formula [(η 6 ‐arene)Ru(L)Cl] + {where, L = L1 , arene = benzene ( 1 ); p ‐cymene ( 2 ); L = L2 , arene = benzene ( 5 ); p ‐cymene ( …
