Crystal structure of beryllium
WebBeryllium and BeCl2 were treated with trifluoromethanesulfonic acid and trimethylsilyltriflate, respectively to form beryllium triflates BeL2(OTf)2 (L=H2O, THF, nBu2O). 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.

Beryllium is a steel gray and hard metal that is brittle at room temperature and has a close-packed hexagonal crystal structure. It has exceptional stiffness (Young's modulus 287 GPa) and a melting point of 1287 °C. The modulus of elasticity of beryllium is approximately 50% greater than that of steel. The combination of this modulus and a relatively low density results in an unusuall…
