The four- and five-co-ordinate iridium(I) cations [Ir(dppe)2]+ and [Ir(CO)(dppe)2]+ react with B10H14, B10H13(Cl-6), and [B10H13]– to give a number of ionic compounds. The reaction between [Ir(dppe)2]Cl and B10H13X (X = H or 6-Cl) yields [IrIIICl(d

The title compound has been isolated as an unexpected product of the reaction between [NMe4][B3H8] and PPh2Cl, and has been examined by 1H, 31P, and 11B n.m.r. spectroscopy and by single-crystal X-ray analysis. The compound crystallizes in colourless

Treatment of But2P(CH2)5PBut2, with iridium trichloride gives a mixture of the 16-atom ring dihydride [lr2H2Cl4{But2P(CH2)5PBut2}2], a co-ordinatively saturated cyclometallated hydride, [[graphic omitted]But2)])(1b), which is non-fluxional, and an un
