C is beta Tridymite-derived structured and crystallizes in the tetragonal I4/mmm space group. There are two inequivalent C sites. In the first C site, C(1) is bonded to two equivalent C(1) and two equivalent C(2) atoms to form edge-sharing CC4 tetrahedra. In the second C site, C(2) is bonded in a linear geometry to one C(1) and one C(2) atom.

In the first C site, C(1) is bonded to two equivalent C(1) and two equivalent C(2) atoms to form edge-sharing CC4 tetrahedra. Both C(1)-C(1) bond lengths are 1.63 Å. Both C(1)-C(2) bond lengths are 1.44 Å. In the second C site, C(2) is bonded in a linear geometry to one C(1) and one C(2) atom. The C(2)-C(2) bond length is 1.20 Å.
