Abstract: The title compound, (Ph₃Te)₂[TeCl₆] or 2C₁₈H₁₅Te⁺·TeCl₆^2-, was obtained as yellow hexagonal crystals from the reaction of Ph₃TeCl with [(Ph₃PO)₂H]₂[Te₂Cl₁₀]. The structure consists of discrete octahedral [TeCl₆]^2- anions, with site symmetry , and trigonal pyramidal (Ph₃Te)⁺ cations, with site symmetry 3. The weak TeCl secondary bonds of 3.527  (1)  Å between the cation and anion expand the TePh₃E coordination of the telluronium tellurium into a distorted TePh₃Cl₃E trigonal prism (E = electron lone pair).
