The latter geometry suggests a configuration for the previously structurally uncharacterised [B10H15](-) anion; starting from this configuration, DFT calculations of structure and thence of boron nuclear shieldings, which are found very closely to mimic those found experimentally, thence support a fluxional structure for [B10H15](-) with three {BHB( bridging)} and two {BH( endo)} hydrogen atoms around a six-membered open face.
