  Crystal structure, luminescence, and thermochromic properties of bis(tetraethylammonium) hexabromotellurate(IV)

  摘要：

  The atomic structure of ((C(2)H(5))(4)N)(2)TeBr(6) crystals (a = 17.930(8) , b = 11.133(5) , c = 15.022(7) , beta = 109.28(9)A degrees, space group C2/c, Z = 4, rho(calcd) = 2.036 g/cm(3)) has been studied by X-ray diffraction. The ((C(2)H(5))(4)N)(2)TeBr(6) crystal structure consists of isolated [TeBr(6)](2-) anions and ((C(2)H(5))(4)N)(+) cations. The electronic and geometric aspects that influence the luminescence and thermochromic properties of the complex have been considered.

  Far-i.r. spectra of salts of [SeX6]2–(X = Cl or Br), and [TeX6]2–(X = Cl, Br, or I), are reported for pressures up to 40 kbar. All observed bands show blue shifts but the most dramatic effects are exhibited by the ν4 bending modes of the anions. For some compounds ν4 is absent at ambient pressure but appears at increased pressure and exhibits a large blue shift, but other compounds which have ν4 initially

The α‖′ values for TeIVX are 40–50% higher than those for SnIVX, from which it is deduced that the a1g* molecular orbital which accommodates the lone pair of s electrons in the case of TeIV is significantly involved in the Te–X bonding.

  of tellurium(IV) oxide with concentrated hydrochloric acid gives a solution from which (Ph4As)2TeCl6 may be precipitated. This material has 125Te Mossbauer parameters which suggest that the anion may be distorted towards, C3v symmetry. By contrast the hexabromotellurate and the hexachlorotellurate formed when a benzene solution of TeCl4 is treated with Ph4AsCl are ‘normal’. TGA studies show that the

  氧化碲（IV）与浓盐酸的反应生成了一种溶液，从该溶液中可以沉淀出（Ph4As）2TeCl6。该材料的参数为125 Te Mossbauer，这表明阴离子可能朝C3v对称方向变形。相比之下，当TeCl4的苯溶液用Ph4AsCl处理时形成的六溴碲酸盐和六氯碲酸盐是“正常”的。TGA研究表明，六氯和六溴代碲酸铵和四甲基铵或多或少干净地分解为四卤化碲和卤化铵。四菌根盐的分解更复杂。
