Abstract
A tetraethylammonium (TEA) salt of TeO42− was synthesized by reacting Te(OH)6 with tetraethylammonium hydroxide. X-ray structural analysis of (TEA)2TeO4·2H2O confirmed that this new compound consists of discrete TeO42− anions of distorted tetrahedral structure together with TEA cations and water molecules of crystallization [a = 8.0820(9) Å, b = 13.7730(12) Å, c = 20.1590(18) Å, V = 2244.0(4) Å3, Z = 4, and space group Pccb]. The 125Te NMR spectrum indicated that water reacts with the TeO42− anion to regenerate octahedral tellurate species in solution.Keywords
