Abstract
The octahydrotriborate(1–) anion, [B3H8]–, reacts with amine and tertiary phosphine complexes of cobalt(I) and cobalt(II) halides to give arachno-triborane-ligand adducts, B3H7L, together with B2H4L2 and BH3L (where L = pyridine or tertiary phosphine). A similar reaction occurs with trans-[RhI(CO)Cl(PPh3)2] and with [IrI(CO)Cl(PPh3)2]. The latter complex also yields the novel ‘borallyl’ compound [IrIII(η3-B3H7)(CO)H(PPh3)2] which may also be described as a nido-iridatetraborane, [(IrB3H7)(CO)H(PPh3)2]. The spectroscopic properties and structure of this compound are discussed. The [B3H8]– ion does not react with [IrI(CO)(dppe)2]+ but [IrI(dppe)2]+ is converted into [IrIIIH2(dppe)2]+(dppe = Ph2PCH2CH2PPh2).Keywords
