C crystallizes in the orthorhombic Cmmm 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 a mixture of corner and edge-sharing CC4 tetrahedra. In the second C site, C(2) is bonded in a trigonal planar geometry to one C(2) and two equivalent C(1) atoms.

In the first C site, C(1) is bonded to two equivalent C(1) and two equivalent C(2) atoms to form a mixture of corner and edge-sharing CC4 tetrahedra. There is one shorter (1.54 Å) and one longer (1.66 Å) C(1)-C(1) bond length. Both C(1)-C(2) bond lengths are 1.50 Å. In the second C site, C(2) is bonded in a trigonal planar geometry to one C(2) and two equivalent C(1) atoms. The C(2)-C(2) bond length is 1.33 Å.
