Reaction of $\mathrm{LiAlH}_{4}$ with one equivalent of $\mathrm{Me}_{3} \mathrm{N} \cdot \mathrm{HCl}$ gives a tetrahedral compound, which reacts with another equivalent of $\mathrm{Me}_{3} \mathrm{N} \cdot \mathrm{HCl}$ to give compound N . The compound N and its geometry, respectively, are:
(a)$\mathrm{LiAlH}_{4} \mathrm{NMe}_{3}$ and trigonal bipyramidal
(b)$\mathrm{AlH}_{3}\left(\mathrm{NMe}_{3}\right)_{2}$ and trigonal bipyramidal
(c)$\mathrm{Li}_{2} \mathrm{AlH}_{4} \mathrm{Cl}$ and square pyramidal
(d)$\mathrm{AlH}_{3}\left(\mathrm{NMe}_{3}\right)_{2}$ and pentagonal
