Materials Data on SrBeSi by Materials Project
SrBeSi crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Sr2+ is bonded to six equivalent Si4- atoms to form a mixture of distorted face, edge, and corner-sharing SrSi6 pentagonal pyramids. All Sr–Si bond lengths are 3.27 Å. Be2+ is bonded in a trigonal planar geometry to three equivalent Si4- atoms. All Be–Si bond lengths are 2.33 Å. Si4- is bonded in a distorted trigonal planar geometry to six equivalent Sr2+ and three equivalent Be2+ atoms.
