MgSiN2 is Chalcopyrite structured and crystallizes in the tetragonal I-42d space group. Mg(1) is bonded to four equivalent N(1) atoms to form MgN4 tetrahedra that share corners with four equivalent Mg(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 Mg(1)N4 tetrahedra. N(1) is bonded to two equivalent Mg(1) and two equivalent Si(1) atoms to form corner-sharing NMg2Si2 tetrahedra.
