In the title compound, tetraethylammonium hydroxide pentahydrate, C(8)H(20)N(+).OH(-).5H(2)O, layers of approximately hexagonally close-packed NEt(4)(+) cations and anionic layers of hydroxide and water molecules are stacked alternately along the b a
Summary The structures of known and of one hypothetical silica sodalite were minimized and the dynamics of the molecular motion of the guest species were investigated.
