dc.description.abstractThe kinetics of the reactions of Ru(II) complexes with CS2N- 3 ions were studied spectrophotometrically. The formation rate constants data for trans-[Ru(NH3)4L(CS2N3)] are 2.2 × 102, 1.8 × 10 and 1.3 × 102 M-1 s-1 for L = SO2- 3, HSO- 3 and P(OEt)3), respectively [μ = 1.0 M (NaCF3COO), 25°C]. Under the same experimental conditions, the values of k-1 (specific rate for the aquation reaction) are 1.5 × 10-2, 5.0 × 10-2 and 4.5 × 10 s-1 for L = SO2- 3, HSO- 3 and P(OEt)3, respectively. The free-energy change (ΔG≠) for the systems where L = P(OEt)3 and SO2- 3 are in agreement within the experimental error. It was observed that the affinity of the CS2N- 3 ion decreases with the increasing π-acidity of the auxiliary ligand L. The order of affinity of the CS2N- 3 ion for the Ru(II) center studies is SO2- 3 > HSO- 3 > P(OEt)3 >SO2. © 1986.en
