Abstract: The structure and electronic properties of a new structural variety of fluorographene were calculated by the density functional theory method. Only one polymorphic variety of fluorographene based on graphene 3-12 is possible, in which all atoms are in equivalent structural positions. The hexagonal unit cell 3-12 of fluorographene contains 12 atoms, the sublimation energy is 13,77 eV/(CF), the band gap is 3,43 eV.

Keywords: graphene, fluorographene, ab initio calculations, crystal structure, electronic properties, polymorphism.
