It is a colourless, hygroscopic solid that dissolves well in many polar solvents. Its properties are similar to those of aluminium chloride, due to beryllium's diagonal relationship with aluminium. ==Structure and synthesis== Beryllium chloride is prepared by reaction of the metal with chlorine at high temperatures:〔Irving R. Tannenbaum "Beryllium Chloride" ''Inorganic Syntheses'', 1957, vol. 5, p. 22. 〕 :Be + Cl2 → BeCl2 BeCl2 can also be prepared by carbothermal reduction of beryllium oxide in the presence of chlorine.〔Cotton, F. A.; Wilkinson, G. (1980) ''Advanced Inorganic Chemistry'' John Wiley and Sons, Inc: New York, ISBN 0-471-02775-8.〕 BeCl2 can be prepared by treating Be metal with hydrogen chloride. BeCl2 The solid is a 1-dimensional polymer consisting of edge-shared tetrahedra.〔Wells, A. F. (1984) ''Structural Inorganic Chemistry'', Oxford: Clarendon Press. ISBN 0-19-855370-6.〕 In contrast, BeF2 is a 3-dimensional polymer, with a structure akin to that of quartz. In the gas phase, it exists both as a linear monomer and a bridged dimer with two bridging chlorine atoms where the beryllium atom is 3-coordinate. The linear shape of the monomeric form is as predicted by VSEPR theory. The linear shape contrasts with the monomeric forms of some of the dihalides of the heavier members of group 2, e.g. CaF2, SrF2, BaF2, SrCl2, BaCl2, BaBr2, and BaI2, which are all non-linear.〔 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「Beryllium chloride」の詳細全文を読む スポンサード リンク
