Abstract: | Photochemical Reactions of Chromium(III) Azido Complexes. Preparation of Nitrido-N, N′-ethylene-bis(salicylideniminato) Chromium(V) Complex The azide to nitride ligand conversion in the coordination sphere of chromium(III) complexes under light of 313 nm excitation has been observed. This photochemical reaction has been used to prepare the nitrido-N, N′-ethylene-bis(salicylideniminato)-chromium(V) complex characterized by an elementar analysis, electron, absorption, IR, and ESR spectra. The results of previous authors that the 313 nm photolysis of Cr(NH3)5N32+ yields Cr2+ or coordinated nitrenes are reinterpreted solely by formation of chromium(V) nitrido species. |
