nido-iridanonaborane species and that cage rearrangement does not occur during the course of the reaction. Similarly, reaction of 1a with H2S under identical conditions results in the formation nido-[2,2,2-(PMe3)2H-2,6-IrSB8H10] (9a), closo-[2,2,2-(PMe3)2H-2,1-IrSB8H8] (10), and nido-[(PMe3)2HIrS2B8H8] (11a) in overall yields of 13%, 7%, and 20%, respectively. Additionally, refluxing a solution of 1a and anhydrous hydrazine
