Materials Data on BeGeAs2 by Materials Project
BeGeAs2 is Chalcopyrite structured and crystallizes in the tetragonal I-42d space group. The structure is three-dimensional. Be2+ is bonded to four equivalent As3- atoms to form BeAs4 tetrahedra that share corners with four equivalent BeAs4 tetrahedra and corners with eight equivalent GeAs4 tetrahedra. All Be–As bond lengths are 2.27 Å. Ge4+ is bonded to four equivalent As3- atoms to form GeAs4 tetrahedra that share corners with four equivalent GeAs4 tetrahedra and corners with eight equivalent BeAs4 tetrahedra. All Ge–As bond lengths are 2.47 Å. As3- is bonded to two equivalent Be2+ and two equivalent Ge4+ atoms to form corner-sharing AsBe2Ge2 tetrahedra.
