${\displaystyle \mathrm {In+Te\longrightarrow InTe} }$

properties

Indium (I, III) telluride is a hot, silver-gray, cold steel-blue, fibrous, easily friable solid that is not noticeably soluble in hydrochloric acid. It crystallizes in a tetragonal layer structure with the space group I 4 / mcm (space group no. 140) . The In ³⁺ ions form chains of edge-linked InTe ₄ tetrahedra. However, the compound also occurs in a cubic modification.
