The crystal structure of an X-type hexaferrite Sr2Co2Fe28O46 was investigated by the x-ray and neutron diffraction methods for a single crystal. Sr2Co2Fe28O46 has the crystal structure described as a space group R\(3\)m (Z = 3) and its lattice constants are a = 5.9165(2) Å and c = 84.1395(33) Å at 843 K. Co ions are almost localized in the octahedral site (9d) in the middle of S*S* blocks. In addition, the adjacent octahedral and tetrahedral sites to 9d site contain the significant number of Co2+.
