Tellurium(IV) Iodide: Tetrameric Te₄I₁₆ Molecules in the Solid

An iodine-127 Mössbauer study of some chalcogen cations of iodine

“…Okuda reported the Iz9I Mossbauer spectrum of TeI, as well as of several other tellurium iodides. The latter workers were able to resolve three independent iodine sites; this finding is consistent with the X-ray crystal structure of TeI, (25). The terminal iodine atom in TeI, was found to have a quadrupole coupling constant of 1190 MHz and an isomer shift with respect to the ZnTe source of 0.70 mm s-I.…”

Synthesis and Crystal Structures of [TeI3][GaI4] and [TeI3][InI4]

“…The Te±I bond distances are slightly shorter than in TeI 4 tetramers[7,8]. When the Te±I bond distances are compared, a slight increase of the average values with the variation of M in the order Al < Ga < In (average values: 2.av) in [TeI 3 ][GaI 4 ] and 3.434 (av) in the indium derivative.…”
