The crystal structure of an X-type hexaferrite Sr $_{2}$ Co $_{2}$ Fe $_{28}$ O $_{46}$ was investigated by the X-ray and neutron diffraction methods for a single crystal. Sr $_{2}$ Co $_{2}$ Fe $_{28}$ O $_{46}$ has the crystal structure described as a space group () and its lattice constants are = 5.9165(2) ; and = 84.1395(33) ; at 843 K. Co ions are almost localized in the octahedral site () in the middle of S $^{*}$ S $^{*}$ blocks. In addition, the adjacent octahedral and tetrahedral sites to site contain the significant number of Co $^{2+}$ .
