A new carborane has been prepared by the gas phase reaction of 1,5- C2B3H5 and diborane at 300C in a flow system. The mass spectral cut-off and profile show it to be a nido-carborane with the empirical formula C2B6H10, while 32-MHz 11B nmr analyses show that it is not a conventional nido-compound but has instead an openarachno-structure as does its isoelectronic analog B8H12. The fact that it has this structure implies that bridge hydrogen placement may be the most important feature in the structuring of boranes and carboranes.
