Structure of bis(tetraethylammonium) molybdate dihydrate obtained by the reaction between ammonium molybdate and tetraethylammonium hydroxide
Abstract
Treatment of ammonium molybdate with tetraethylammonium hydroxide produces tetraethylammonium molybdate that can be recrystallized from acetonitrile/ether. The crystal structure reveals the dihydrate compound (C 8 H 20 N) 2 [MoO 4 ]·2H 2 O. The presence of water molecules in the structure is further supported by FTIR, which demonstrates the corresponding broad signal centered around 3225 cm −1 . The supramolecular structure of (Et 4 N) 2 [MoO 4 ]·2H 2 O demonstrates two-dimensional layers of tetrahedral molybdate molecules bridged by water molecules, with each Mo-oxo serving as a hydrogen-bond acceptor. The molybdate/water layers are spaced by the layers of disordered tetraethylammonium counter-ions. The structural parameters of (Et 4 N) 2 [MoO 4 ]·2H 2 O are presented at 100 and 200 K.
