Materials Data on BeSnP2 by Materials Project

BeSnP2 is Chalcopyrite structured and crystallizes in the tetragonal I-42d space group. The structure is three-dimensional. Be2+ is bonded to four equivalent P3- atoms to form BeP4 tetrahedra that share corners with four equivalent BeP4 tetrahedra and corners with eight equivalent SnP4 tetrahedra. All Be–P bond lengths are 2.20 Å. Sn4+ is bonded to four equivalent P3- atoms to form SnP4 tetrahedra that share corners with four equivalent SnP4 tetrahedra and corners with eight equivalent BeP4 tetrahedra. All Sn–P bond lengths are 2.54 Å. P3- is bonded to two equivalent Be2+ and two equivalent Sn4+ atoms to form distorted corner-sharing PBe2Sn2 tetrahedra.
