Synthesis and structures of photodecarbonylated ruthenium(II) complexes—potential intermediates for mixed ligand complexes

Abstract

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).
