BeSiP2 is Chalcopyrite structured and crystallizes in the tetragonal I-42d space group. Be(1) is bonded to four equivalent P(1) atoms to form BeP4 tetrahedra that share corners with four equivalent Be(1)P4 tetrahedra and corners with eight equivalent Si(1)P4 tetrahedra. Si(1) is bonded to four equivalent P(1) atoms to form SiP4 tetrahedra that share corners with four equivalent Si(1)P4 tetrahedra and corners with eight equivalent Be(1)P4 tetrahedra. P(1) is bonded to two equivalent Be(1) and two equivalent Si(1) atoms to form corner-sharing PBe2Si2 tetrahedra.
