|Title:||Role of ambidentate thiocyanate in the formation of linkage isomers via substiution of halides in chIoro- and bromo-pentaammineruthenium(III) ions|
|Abstract:||Reactions of chloro- and bromo-pentammineruthenium(III) complex ions with thiocyanate ion have been investigated spectrophotometrically between 65° and 75°C to determine the nature of linkage of the entering ligand thiocyanate. Rate constants have been evaluated by the Guggenheim's procedure which shows linearity upto 2-3 half lives. Both the complexes show SCN- independent (k1) and SCN- dependent (k2)paths. The k1-path virtually represents equation of the complex. The k1-path involves direct exchange of ligands without any solvent participation. The product complex is always the N-bonded isomer.|
