Tellurium iodide is an inorganic compound with the formula TeI.
[2] TeI is a gray solid formed by the hydrothermal reaction of tellurium metal and iodine in hydroiodic acid.
When the same mixture is heated to 150 °C, one obtains the metastable monoclinic phase β-TeI.
[3] The compounds are related structurally to Te2I (see ditellurium bromide), but the additional iodide groups do not bridge to other Te centers.
[2] Although TeI2 has not been isolated in bulk, complexes of the type TeI2(thiourea)2 are well characterized.
