The structure described by BeSiN2 is Chalcopyrite structured and crystallizes in the tetragonal I-42d space group. Be(1) is bonded to four equivalent N(1) atoms to form BeN4 tetrahedra that share corners with four equivalent Be(1)N4 tetrahedra and corners with eight equivalent Si(1)N4 tetrahedra. Si(1) is bonded to four equivalent N(1) atoms to form SiN4 tetrahedra that share corners with four equivalent Si(1)N4 tetrahedra and corners with eight equivalent Be(1)N4 tetrahedra. N(1) is bonded to two equivalent Be(1) and two equivalent Si(1) atoms to form corner-sharing NBe2Si2 tetrahedra. is represented by the CIF file [CIF]
