Abstract

The metathesis reaction of TeBr4 and AgSb(OTeF5)6 in SO2 led to [TeBr3][Sb(OTeF5)6] and AgBr, and that of 2AgSb(OTeF5)6 with 7Te:TeBr4 led to [Te4][Sb(OTeF5)6]2. The crystal structure of [Cl3Te-F-TeCl3][Sb(OTeF5)6] is reported, prepd. from Te, TeBr4 and AgSb(OTeF5)6 in SO2ClF. [Cl3Te-F-TeCl3][Sb(OTeF5)6] crystallizes in space group P.hivin.1 with a = 10.144(6), b = 10.462(2), c 9.023(4) .ANG., a 93.38(2), b 104.42(4), g 83.06(3) Deg, V = 920.3(5) .ANG.3 and Z = 2. The structure consists of isolated fluoride bridged [Cl3Te-F-TeCl3]+ cations and [Sb(OTeF5)6]- anions with some cation-anion interactions. The obsd. structure and FT-Raman spectrum of [Cl3Te-F-TeCl3]+ are in agreement with that predicted by theor. calcns. (B3PW91/3-21G*). [on SciFinder (R)]

Crystal structure

In crystallography, crystal structure is a description of the ordered arrangement of atoms, ions, or molecules in a crystalline material. Ordered structures occur from the intrinsic nature of the constituent particles to form symmetric patterns that repeat along the principal directions of three-dimensional space in matter. The smallest group of particles in the material that constitutes this repeating pattern is the unit cell of the structure.

Tellurium

Tellurium is a chemical element with the symbol Te and atomic number 52. It is a brittle, mildly toxic, rare, silver-white metalloid. Tellurium is chemically related to selenium and sulfur, all three of which are chalcogens. It is occasionally found in its native form as elemental crystals. Tellurium is far more common in the Universe as a whole than on Earth. Its extreme rarity in the Earth's crust, comparable to that of platinum, is due partly to its formation of a volatile hydride that caused tellurium to be lost to space as a gas during the hot nebular formation of Earth.

Metalloid

A metalloid is a type of chemical element which has a preponderance of properties in between, or that are a mixture of, those of metals and nonmetals. There is no standard definition of a metalloid and no complete agreement on which elements are metalloids. Despite the lack of specificity, the term remains in use in the literature of chemistry. The six commonly recognised metalloids are boron, silicon, germanium, arsenic, antimony and tellurium. Five elements are less frequently so classified: carbon, aluminium, selenium, polonium and astatine.
