Abstract

Single-crystal X-ray diffraction studies on [C2B10H10C4H4](‘benezocarborane’) and C2B10H10C4H6(‘dihydrobenzocarborane’) show that the C6 rings of each posses localised double bonds and this has been confirmed by bond-order calculations: the nido-anion. [C2B9H10C4H4]– synthesised from C2B10H10C4H4, with maleic anhydride forms a Diels-Alder adduct.
