The thermal and photochemical pathway of compound 1 [6-(η5-C5Me5)-nido-6-RhB9H13] is reported. Under thermal conditions, compound 1 was converted to [hypercloso-(η5-C5Me5)RhB9H9] (2) through the loss of two dihydrogen molecules in toluene. In contrast, under UV irradiation, compound 1 undergoes reactions in benzene to give the previously known compound [nido-5-(η5-C5Me5)RhB9H13] (3). The hypercloso compound 2 is the first Rhodium containing hypercloso-metalladecaborane, while the photochemically induced isomerization is unprecedented. The compounds were identified using spectroscopic methods.
