Irradiation of solutions containing complexes of the type [RuL(CO)2Cl2] where L is a 2,2′-bipyridine analogue leads to monodecarbonylation and the formation of dimeric ruthenium(II) complexes, [RuL(CO)2Cl]2, for which two different structures have been established, viz. with a trans disposition of bridging and terminal chlorides [L = di(2-pyridyl) ketone] or with CO trans to bridging chlorides (L = 1,10-phenanthroline).
