|Section3= |Section7= |Section8= }} Bismuth(III) iodide is the inorganic compound with the formula BiI3. This gray-black solid is the product of the reaction of bismuth and iodine, which once was of interest in qualitative inorganic analysis. 〔 〕 〔 〕 Bismuth(III) iodide adopts a distinctive crystal structure, with iodide centres occupying a hexagonally closest-packed lattice, and bismuth centres occupying either none or two-thirds of the octahedral holes (alternating by layer), therefore it is said to occupy one third of the total octahedral holes. 〔 〕 〔 〕 ==Synthesis== Bismuth(III) iodide forms upon heating an intimate mixture of iodine and bismuth powder: :2Bi + 3I2 → 2BiI3 BiI3 can also be made by the reaction of bismuth oxide with aqueous hydroiodic acid: :Bi2O3(s) + 6HI(aq) → 2BiI3(s) + 3H2O(l) 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「Bismuth(III) iodide」の詳細全文を読む スポンサード リンク
