The reaction of Vaska's complex with 1 equiv of Na[HB(mt)(3)] or Na[H2B(mt)(2)] (mt = methimazolyl) affords the iridaboratranes [IrH(CO)(PPh3)kappa(3)-B,S,S'-B(mt(2))R}](Ir-I -> B) (R = mt, H), the first examples of metallaboratranes in which the transannular metal -> boron bond is supported by only two methimazolyl buttresses.
