| Abstract: | The reactions of [RuCl3(AsPh3)3] with ligands containing nitrogen (alkyl and aryl cyanides, pyridine, α-picoline N.N′-bipyridyl, 1,10-phenanthroline), oxygen (ketones, aldehydes, N,N-dimethylformamide, tetrahydrofuran, dimethylsulphoxide and nitroalkanes) and sulphur (CS2 and Me2S) donor atoms have been studied. The reactions of [RuCl3(AsPh3)3] with tetra alkyl and aryl ammonium and arsonium salts have also been explored. The compounds obtained have been characterised by analyses, conductivity measurements, magnetic measurements and IR spectra. The electronic spectra of the complexes are discussed in terms of possible structures. An equilibrium between hexacoordinated and pentacoordinated species is suggested on the basis of electronic spectral studies. |
