Materials Data on BeSO4 by Materials Project

BeSO4 is quartz (alpha)-derived structured and crystallizes in the tetragonal I-4 space group. The structure is three-dimensional. Be2+ is bonded to four equivalent O2- atoms to form BeO4 tetrahedra that share corners with four equivalent SO4 tetrahedra. All Be–O bond lengths are 1.63 Å. S6+ is bonded to four equivalent O2- atoms to form SO4 tetrahedra that share corners with four equivalent BeO4 tetrahedra. All S–O bond lengths are 1.48 Å. O2- is bonded in a distorted bent 150 degrees geometry to one Be2+ and one S6+ atom.
