Abstract Beryllium and BeCl2 were treated with trifluoromethanesulfonic acid and trimethylsilyltriflate, respectively to form beryllium triflates BeL2(OTf)2 (L=H2O, THF, n Bu2O). The Be–O atomic distances (1.605–1.635 Å) between Be2+ and the triflate anions in solid state are the shortest known distances of this kind in a metal triflate yet. Attempts to remove the solvate molecules led to the decomposition of the obtained compounds.

铍三氟甲磺酸盐：BeL2(OTf)2 (L=H2O, THF, nBu2O) 的合成和结构

摘要 铍和BeCl2 分别用三氟甲磺酸和三甲基甲硅烷基三氟甲磺酸酯处理，生成铍三氟甲磺酸酯BeL2(OTf)2 (L=H2O, THF, n Bu2O)。Be2+ 与固态三氟甲磺酸根阴离子之间的 Be-O 原子距离 (1.605–1.635 Å) 是迄今为止金属三氟甲磺酸根中已知的最短距离。去除溶剂化物分子的尝试导致所得化合物的分解。
