The material structure described by BeSnAs2 is Chalcopyrite structured and crystallizes in the tetragonal I-42d space group. Be(1) is bonded to four equivalent As(1) atoms to form BeAs4 tetrahedra that share corners with four equivalent Be(1)As4 tetrahedra and corners with eight equivalent Sn(1)As4 tetrahedra. Sn(1) is bonded to four equivalent As(1) atoms to form SnAs4 tetrahedra that share corners with four equivalent Sn(1)As4 tetrahedra and corners with eight equivalent Be(1)As4 tetrahedra. As(1) is bonded to two equivalent Be(1) and two equivalent Sn(1) atoms to form corner-sharing AsBe2Sn2 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
