It is a white, hygroscopic solid. In addition to the anhydrous ThCl4, two hydrates have been reported: ThCl4(H2O)4〔Cantat, Thibault; Scott, Brian L.; Kiplinger, Jaqueline L. "Convenient Access to the Anhydrous Thorium Tetrachloride Complexes ThCl4(DME)2, ThCl4(1,4-dioxane)2 and ThCl4(THF)3.5 using Commercially Available and Inexpensive Starting Materials" Chemical Communications 2010, 46, 919-921. 〕 and ThCl4(H2O)8.〔P. Ehrlich "Titanium, Zirconium, Hafnium, and Thorium" in Handbook of Preparative Inorganic Chemistry, 2nd Ed. Edited by G. Brauer, Academic Press, 1963, NY. Vol. 1. p. 1203.〕 These salts are water-soluble and also white. ==Preparation and structure of anhydrous thorium(IV) chloride== The anhydrous tetrachloride is prepared by carbothermic reaction of thorium dioxide:〔 :ThO2 + 2 C + 4 Cl2 → ThCl4 + 2 CO In terms of its chemical structure, the anhydrous compound features 8-coordinate, giving overall dodecahedron geometry.〔R. C. L. Mooney: „The Crystal Structure of ThCl4 and UCl4“, in: ''Acta Crystallographica'', 1949, ''2'', S. 189–191 ().〕 Thorium(IV) tetrabromide is isostructural. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Thorium(IV) chloride」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
