Abstract
By single crystal X-ray analysis, the atomic structure of the crystals of bis-phenanthrolinium hexachlorotellurate(IV) dihydrate (С12Н9N2)2TeBr6·2H2O (a = 7.4846(5) Å, b = 13.792(1) Å, c =
14.532(1) Å, β = 99.857(2)°, space group Р21/c, Z = 2, dx = 2.259 g/cm3) is determined. The crystal structure is formed from separate anions [TeBr6]2-, cations of phenanthrolinium (С12Н9N2)+, and water molecules. The electronic and geometrical aspects determining the spectral-luminescent and thermochromic properties of the complex are discussed.
