Crystal structure of beryllium
WebThe beryllium boride, Be/sub 4/N, was formed by sintering pressed compacts at 850 to 950 deg C under inert gas. The crystal structure was determined by Fourier analysis of x-ray data. An atomistic interpretation of the Be/sub 4/B structure is discussed. (TCO) 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.
