The material structure described by SiC2 crystallizes in the tetragonal P4_2/mmc space group. Si(1) is bonded to four equivalent C(1) atoms to form corner-sharing SiC4 tetrahedra. C(1) is bonded in a trigonal planar geometry to two equivalent Si(1) and one C(1) atom. is represented by the CIF file [CIF]
