Structure and reactivity of transition-metal complexes with polyatomic ligands. Part V. Electron spin resonance spectra of intermediates and some kinetic results for the acid hydrolysis of [Cr(CN)5NO]3–

Three intermediates in the acid hydrolysis of [Cr(CN)5NO]3– are detected in solution by e.s.r. at room temperature, the final product being [Cr(NO)(H2O)5]2+. Each species is characterised by different A(14N), A(53Cr), or g values. Kinetics of the last two stages of the reaction have been studied to determine the dependence of reaction rates on acid concentration and to evaluate the activation parameters.
