To understand the principles of operation of polynuclear complexes and possibly improve their performance, the tunabil-ity of photophysical and redox properties has been examined in a number of such complexes. These complexes are composed of polypyridyl units of Ru and Os as chromophores and cyanide as the bridging ligand [76]. By appropriate synthetic procedures, it is possible to control the mode of coordination of the bridging cyanide to a given chromophoric unit as a nitrile (C-bonded) or isonitrile (N-bonded) [74-77]. By varying the nature of... 

ISOCYANIDES AND NITRILE LIGANDS IN POLYNUCLEAR LINEAR COMPLEXES... 

Ligands containing triple bonds — C = Y and — Y = C are nitriles RC = N, phosphaalkynes RC = P, and isocyanides R —N = C. All these ligands form mono-and polynuclear n complexes with transition metals.The reaction of [Pt(/ra .s-PhCH = CHPh)(PPh3)2] with trifluoroacetonitrile affords a n complex possessing the following structure.
