Studies of the reactions of thiocyanate ion with pentammine dinitrogen ruthenium(II) dibromide at different temperatures

The salts of the linkage isomers of thiocyanatopentammineruthenium(III) [Ru(NH 3 ) 5 ( N CS)] 2+ , [Ru(NH 3 ) 5 ( S CN)] 2+ and dithiocyanatotetrammineruthenium(III) [Ru(NH 3 ) 4 (NCS) 2 ] + along with those of tetrathiocyanatodiammineruthenate(III) [Ru(NH 3 ) 2 (SCN) 4 ] − have been synthesized. The insoluble polymeric complex [Ru(NH 3 ) 2 (SCN) 2 ] n has also been prepared. The compounds have been characterized by chemical analyses, spectral (IR, UV and visible), magnetic susceptibility, conductivity, cyclic voltammetry and chromatography studies.
