Photoinduced solid-state isomerization and structural characterization of a nitro–nitrosyl ruthenium complex with 3-cyanopyridine

The title complex, which is crystallized in a noncentrosymmetric space group due to specific intermolecular interactions, exhibits reversible light-induced nitrosyl linkage isomerism; thus, it is of interest for studying combined Ru–NO ↔ Ru–ON isomerization with non-linear optical properties.
