Abstract

The photochemistry of [Ru(CO)₅] with a series of nitrogen heterocycles has been investigated in dichloromethane solution. Photolysis with pyridine (py) leads to the highly unstable novel monosubstituted complex [Ru(CO)₄(py)]. In the case of polydentate heterocycles, photooxidation occurs. With 2,2′-bipyridine a number of complex products are generated. With 2,2′:6,2″-terpyridine (terpy), [RuCl₃(terpy)] is formed. With 6-(2-thienyl)-2,2′-bipyridine (thbipy), [RuCl₃(thbipy)] is formed, this being soluble in donor solvents generating [RuCl₃-(thbipy)(solv)] (solv = solvent). The molecular structures of thbipy, [RuCl₃(thbipy)(dmf)] (dmf = dimethylformamide) and [RuCl₃(thbipy)(MeCN)] have been determined by single-crystal X-ray diffraction methods.
