2020年11月13日 · The synthesis of a second beryllium bromide modification, β-BeBr 2, was accomplished through recrystallization of α-BeBr 2 from benzene in the presence of cyclo -decamethylpentasiloxane. This phase was analyzed via single-crystal X-ray diffraction and IR and Raman spectroscopy as well as density functional theory calculations.

2011年1月8日 · Beryllium bromide, BeBr 2, is a binary compound of beryllium and bromine. It is used as an adhesive for polyvinyl alcohol.

BeBr2 is Silicon Disuphide structured and crystallizes in the orthorhombic Ibam space group. The structure is one-dimensional and consists of two BeBr2 ribbons oriented in the (1, 0, 0) direction. Be2+ is bonded to four equivalent Br1- atoms to form edge-sharing BeBr4 tetrahedra. All Be–Br bond lengths are 2.20 Å.

2018年6月16日 · Here we present a facile synthesis for anhydrous BeCl 2, BeBr 2 and BeI 2 from the elements under mild conditions. While this method delivers pure BeI 2 directly, BeCl 2 and BeBr 2 were further purified by vacuum sublimation.

2023年11月13日 · BeBr 2 (beryllium bromide) has one beryllium atom and two bromine atoms. In the BeBr 2 Lewis structure, there are two single bonds around the beryllium atom, with two bromine atoms attached to it, and on each bromine atom, there are three lone pairs. Here’s how you can easily draw the BeBr 2 Lewis structure step by step:
