Materials Data on BeSe by Materials Project

BeSe is Halite, Rock Salt structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Be2+ is bonded to six equivalent Se2- atoms to form a mixture of corner and edge-sharing BeSe6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Be–Se bond lengths are 2.46 Å. Se2- is bonded to six equivalent Be2+ atoms to form a mixture of corner and edge-sharing SeBe6 octahedra. The corner-sharing octahedral tilt angles are 0°.
