The atomic structure of ((C2H5)4N)2TeBr6 crystals (a = 17.930(8) Å, b = 11.133(5) Å, c = 15.022(7) Å, β = 109.28(9)°, space group C2/c, Z = 4, ρcalcd = 2.036 g/cm3) has been studied by X-ray diffraction. The ((C2H5)4N)2TeBr6 crystal structure consists of isolated [TeBr6]2− anions and ((C2H5)4N)+ cations. The electronic and geometric aspects that influence the luminescence and thermochromic properties of the complex have been considered.
