Nitric-oxide photorelease and photoinduced linkage isomerism on solid [Ru(NO)(terpy)(L)]BPh4 (L = glycolate dianion).
Following photoexcitation at 80 K, two phenomena were detected on solid samples of a single substance, the tetraphenylborate of the [Ru(NO)(terpy)(L)](+) cation (terpy = 2,2':6',2''-terpyridine, L = glycolate(2-) [oxyacetate]): the formation of photoinduced linkage isomers of the nitrosyl ligand, and photorelease of nitric oxide. Populations of about 9% and 4% were measured for the photoinduced isonitrosyl (MS1) and the side-on nitrosyl (MS2) linkage isomers, respectively. At room temperature, NO release in the solid was observed as the only reaction.
