The crystal structure described by C is diamond-like structured and crystallizes in the hexagonal P6_3/mmc space group. There are four inequivalent C sites. In the first C site, C(1) is bonded to one C(1) and three equivalent C(3) atoms to form corner-sharing CC4 tetrahedra. In the second C site, C(2) is bonded to one C(2) and three equivalent C(4) atoms to form corner-sharing CC4 tetrahedra. In the third C site, C(3) is bonded to one C(4) and three equivalent C(1) atoms to form corner-sharing CC4 tetrahedra. In the fourth C site, C(4) is bonded to one C(3) and three equivalent C(2) atoms to form corner-sharing CC4 tetrahedra. is represented by the CIF file [CIF]
