Tellurium oxide Specification

The Tellurium oxide, with CAS registry number 13451-18-8, has the systematic name of oxotellane dioxide. This chemical is an inorganic chemical compound of tellurium and oxygen. And the Tellurium oxide has two forms: α-TeO₃ and β-TeO₃. The α-TeO₃ is yellow-red and the other one is grey, rhombohedral. What's more, its EINECS is 231-193-1.

Physical properties of Tellurium oxide: (1)#H bond acceptors: 3; (2)#H bond donors: 0; (3)#Freely Rotating Bonds: 0; (4)Polar Surface Area: 51.21 Å².

There are two differents ways of preparation about the two forms: α-TeO₃ and β-TeO₃. The α-TeO₃ can be prepared by heating orthotelluric acid, Te(OH)₆ at over 300°C . The β-TeO₃ form can be prepared by heating α-TeO₃ in a sealed tube with O₂ and H₂SO₄.

You can still convert the following datas into molecular structure:
(1)SMILES: O=[Te](=O)=O
(2)InChI: InChI=1/O3Te/c1-4(2)3
(3)InChIKey: IIXQANVWKBCLEB-UHFFFAOYAH
(4)Std. InChI: InChI=1S/O3Te/c1-4(2)3
(5)Std. InChIKey: IIXQANVWKBCLEB-UHFFFAOYSA-N
