Monocarbaborane chemistry. Preparation and characterisation of [4-CB8H9], the ‘missing’ closo-carbaborane anionElectronic supplementary information (ESI) available: NMR spectroscopy and calculated coordinates for the B3LYP/6-31G* symmetry-locked structure for [CB8H9]. See http://www.rsc.org/suppdata/cc/b1/b103408c/Systematic IUPAC nomenclature: the closo-4-carbanonaborate(1−) anion; characterised crystallographically as its methyltriphenylphosphonium salt.

Abstract

Thermolysis in the solid state of Cs+[arachno-CB9H14], or of Cs+[nido-CB9H12], or the oxidation of nido-1-CB8H12 with I2 in THF at −78 °C in the presence of NEt3, gives the first nine-vertex closo monocarbaborane, the stable [closo-4-CB8H9] anion, in yields of 56, 61 and 75%, respectively.
