Indium, chalcogenide halides

Again, the complete series of InYX compounds (Y = S,Se,Te X = Cl,Br,I) exists. Of the Group IIIA chalcogenide halides, the indium compounds have been the most extensively studied. 

Indium chalcogenide chlorides and bromides are obtained by heating mixtures of the chalcogenide and the halide in sealed ampoules to temperatures between 200 and 420°C (see Table XIX). For the preparation of the chalcogenide iodides. In and I2 are used instead of Inlj. InTel may be synthesized directly from the elements (161).
