简介
The irradiation of ruthenium−sulfur dioxide complexes of general formula trans-[RuII(NH3)4(SO2)X]Y with laser light at low temperature results in linkage isomerization of SO2, starting with η1-planar S-bound to η2-side S,O-bound SO2. The solid-state photoreaction proceeds with retention of sample crystallinity. Following work on trans-[Ru(NH3)4Cl(η1-SO2)]Cl and trans-[Ru(NH3)4(H2O)(η1-SO2)](C6H5SO3)2 (Kovalevsky, A. Y.; Bagley, K. A.; Coppens, P. J. Am. Chem. Soc. 2002, 124, 9241−9248), we describe photocrystallographic, IR, DSC, and theoretical studies of trans-[RuII(NH3)4(SO2)X]Y complexes with (X = Cl-, H2O, or CF3COO- (TFA-)) and a number of different counterions (Y = Cl-, C6H5SO3-, Tos-, or TFA-). Low temperature IR experiments indicate the frequency of the asymmetric and symmetric stretching vibrations of the Ru-coordinated SO2 to be downshifted by about 100 and 165 cm-1, respectively …
