CoSiN2 is Chalcopyrite structured and crystallizes in the tetragonal I-42d space group. Co(1) is bonded to four equivalent N(1) atoms to form CoN4 tetrahedra that share corners with four equivalent Co(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 Co(1)N4 tetrahedra. N(1) is bonded to two equivalent Co(1) and two equivalent Si(1) atoms to form corner-sharing NCo2Si2 tetrahedra.
