Photo-induced metastable linkage isomers of ruthenium nitrosyl porphyrins
Abstract
IR spectroscopic results, combined with earlier crystallographic and spectroscopic evidence on Fe and Ru nitrosyl complexes, indicate that metastable η1-O and η2-NO linkage isomers are formed on low-temperature irradiation of the nitrosyl metalloporphyrins (OEP)Ru(NO)L (L = O-i-C5H11, SCH2CF3); the new compounds are stable at low temperature, but revert to the ground state on warming.
