|Section2= |Section3= |Section4= |Section8= }} Caesium bromide, (CsBr), is an ionic compound of caesium and bromine. It has simple cubic p-type cubic crystallic structure, comparable to that of caesium chloride type with space group ''Pmm'' and lattice constant ''a'' = 0.42953 nm. The distance between Cs+ and Br− ions is 0.37198 nm. == Synthesis == It can be prepared via following reactions: * Neutralization: : CsOH (aq) + HBr (aq) → CsBr (aq) + H2O (l) : Cs2(CO3) (aq) + 2 HBr (aq) → 2 CsBr (aq) + H2O (l) + CO2 (g) * Direct synthesis: : 2 Cs (s) + Br2 (g) → 2 CsBr (s) The direct synthesis is a vigorous reaction of caesium with other halogens. Due to its high cost, it is not used for preparation. 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「caesium bromide」の詳細全文を読む スポンサード リンク
