Neutral Ru(II) complexes with the formula trans-[Ru(trpy*)(L,)(pcyd)] have been prepared, where trpy* = 4,4',4"-tri-tert-butyl-ter-pyridine, L, = 2-pyrazinecarboxylato (pca), 2-pyridinecarboxylato (pic), acetylacetonato (acac) and pcyd = 3-chlorophenylcyanamido (3-Clpcyd), 2,3-dichlorophenylcyanamido (2.3-Clpcyd), 2,4,6-trichlorophenylcyanamido (2,4,6-Cl(3)pcyd), 2,3,4,5-tetrachlorophenylcyanamido (2,3,4,5-Cl(4)pcyd) and 3,4,5-trimethoxyphenylcyanamido (3,4,5-(OMe)(3)pcyd). Spectroelectrochemistry was performed oil these Ru(II) complexes to obtain the visible absorption spectrum of the Ru(III)-cyanamide ligand-to-metal charge transfer chromophore. The Ru(III)-cyanamide metal-ligand coupling elements of these complexes were compared to other Ru(III)-cyanamide complexes. (c) 2005 Published by Elsevier B.V..
