The material described by CdSiN2 is Chalcopyrite structured and crystallizes in the tetragonal I-42d space group. Cd(1) is bonded to four equivalent N(1) atoms to form distorted CdN4 tetrahedra that share corners with four equivalent Cd(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 Cd(1)N4 tetrahedra. N(1) is bonded to two equivalent Cd(1) and two equivalent Si(1) atoms to form distorted corner-sharing NCd2Si2 trigonal pyramids. is represented by the CIF file [CIF]
