The material structure described by 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 corner-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. is represented by the CIF card [CIF]
