摘要
Raman spectra have been obtained over a range of temperatures for molten and solid InCl2, molten and solid In2Cl3, and InCl dissolved in the molten LiCl-KCl eutectic. It is shown that InCl2 has the constitution In+InCl4- in the liquid and probably also in the solid state. The spectra of molten In2Cl3 and molten InCl.4(Li,K)Cl both show the presence of In (III) chloro complexes and it is concluded that there is disproportionation of In+ in the presence of free chloride and that In0 coordinates with InIIICl4- to form metal-metal bonds. A strong, polarized Raman band at ca. 170 cm-1 is assigned to an In-In stretching mode. © 1969, American Chemical Society. All rights reserved.
