{RuNO}6vs. co-ligand oxidation: two non-innocent groups in one ruthenium nitrosyl complex

2 September, 2014 - 07:54

Dalton Trans., 2014, 43,13835-13838
DOI: 10.1039/C4DT01388C, CommunicationAshley B. McQuarters, Nicolai Lehnert
The one-electron oxidation of the {RuNO}6 complex [Ru(L)(PPh3)(NO)(Cl)]2+ (where L = 1-phenyl-1-(pyridin-2-yl)-2-(pyridin-2-ylmethylene)hydrazine) leads to the generation of a co-ligand radical. This complex therefore represents a rare example of a ruthenium complex with two different non-innocent ligands bound.
