The complexes trans-[Ru(py)4L2] where py = pyridine and L = (2-chlorophenyl)-, (2,3-dichlorophenyl)-, (2,4,5- trichlorophenyl)-, (2,3,4,5-tetrachlorophenyl)- and (pentachlorophenyl)cyanamide were synthesized and characterized by electronic and (1)H NMR spectroscopies. A crystal structureof trans-[Ru(py)4((2-chlorophenyl)cyanamide)2] showed the expected tran s coordination of the phenylcyanamide ligands. Crystal structure data: space group C2/c, with a, b, and c = 40.6441(3), 9.2003(1), and 22.6946(2)?, respectively, β = 116.387(1)°, V = 7602.2(1)?**3, and Z = 8. The structure was refined by using 4943 independent reflections with I > 2σ(I) to a final R factor of 0.060. Spectroelectrochemistry was used to generate the electronic absorption spectra of the Ru(III) complexes trans-[Ru(py)4L2](+). Ru(III)-cyanamide coupling elements derived from charge transfer spectral data of the trans-[Ru(py)4L2](+)complexes were significantly larger than those of the corresponding [Ru (NH3)5L](2+) complexes.
