C is diamond-like structured and crystallizes in the hexagonal P6_3/mmc space group. There are three inequivalent C sites. In the first C site, C(1) is bonded to one C(2) and three equivalent C(3) atoms to form corner-sharing CC4 tetrahedra. In the second C site, C(2) is bonded to one C(1) and three equivalent C(2) atoms to form corner-sharing CC4 tetrahedra. In the third C site, C(3) is bonded to one C(3) and three equivalent C(1) atoms to form corner-sharing CC4 tetrahedra.

In the first C site, C(1) is bonded to one C(2) and three equivalent C(3) atoms to form corner-sharing CC4 tetrahedra. The C(1)-C(2) bond length is 1.54 Å. All C(1)-C(3) bond lengths are 1.54 Å. In the second C site, C(2) is bonded to one C(1) and three equivalent C(2) atoms to form corner-sharing CC4 tetrahedra. All C(2)-C(2) bond lengths are 1.54 Å. In the third C site, C(3) is bonded to one C(3) and three equivalent C(1) atoms to form corner-sharing CC4 tetrahedra. The C(3)-C(3) bond length is 1.57 Å.
