Description
Emily L. Trew and three colleagues report in 2026 a family of rhodium and iridium complexes built around an unusual nitrogen-rich ligand. The ligand, an azidophosphonamide, grips a metal through different nitrogen atoms, and light can flip which grip it uses: linkage isomerism. The team prepared complexes carrying bulky adamantyl or mesityl groups, paired with cyclooctadiene, cyclooctene, or carbon monoxide, then probed for stability.
In the cyclooctadiene complexes, the ligand bound through its first two nitrogens in an extended shape. Ultraviolet light at 365 nanometers flipped them to the alternative pairing without shedding nitrogen gas. Swapping in carbon monoxide kept the extended shape in the solid state. One rhodium cyclooctene complex instead held the ligand in a folded shape, the first stable folded phosphazide seen on a group 9 metal. Light made it expel nitrogen gas to form a new compound. Structures were confirmed by NMR and X-ray crystallography.
