Шаблон:Short description Шаблон:Chembox Indium(I) chloride (also indium monochloride) is the chemical compound with the formula InCl. Indium monochloride occurs as a yellow cubic form below 120 °C and above this temperature as a red orthorhombic form.[1] InCl is one of three known indium chlorides.
Synthesis and structure
InCl can be prepared by heating indium metal with indium trichloride in a sealed tube.[2][3]
According to X-ray crystallography, the structure of the yellow polymorph resembles that of sodium chloride except that the Cl-In-Cl angles are not 90°, but range between 71 and 130°. The red (high T) polymorph crystallizes in the thallium(I) iodide motif.[4][5]
Reactivity
The relatively high energy level of the 5s electrons of the indium center make InCl susceptible to oxidation as well as disproportionation into In(0) and InCl3.[1] Tetrahydrofuran (THF) appears to facilitate the disproptionation of InCl as well as other indium(I) halides.[1]
History
Indium(I) chloride was first isolated in 1926 as part of an investigation on the compounds formed between indium and chlorine.[6]
