BeCl2 is Silicon Disuphide structured and crystallizes in the orthorhombic Ibam space group. The structure is one-dimensional and consists of two BeCl2 ribbons oriented in the (1, 0, 0) direction. Be2+ is bonded to four equivalent Cl1- atoms to form edge-sharing BeCl4 tetrahedra. All Be–Cl bond lengths are 2.04 Å. Cl1- is bonded in an L-shaped geometry to two equivalent Be2+ atoms.
Studies were made on the electrolysis of a molten BeCl2-NaCl bath using a mercury cathode and beryllium anode. A quasi-amalgam was obtained. The beryllium was consolidated by direct hot pressing of the amalgam at temperatures in the range of 800 C and using pressures of 5,000, 10,000 and 20,000 psi. The work confirms the ability to produce ultrafine beryllium particles by electrolysis.
