Figure 13.11c shows ihe solid state structure of the [A1(BH4)4]~ ion, present in [Ph3MeP][AI(BH4)4], In the light of these structural data, account for the following observations, recorded for the compound in solution,
(a) At 298 K, the 'H NMR spectrum of [Ph3MeP][Al(BH4)4] shows one broad signal in addition to signals assigned to the cation; this pattern of signals is retained at 2O3 K.
(b) In the 'B NMR spectrum (298 K) of the same compound, a quintet is observed,
(c) In the IR spectrum of [Ph3MeP][Al(BH4)4], absorptions due to bridging Al—H—B and terminal B—H interactions are both observed.
