The nuclear resonant part of the polarizability tensor is considered which describes the diffraction of Mössbauer radiation by crystals with a combined hyperfine interaction on nuclei. Its Cartesian form is represented for the dipole and quadrupole transitions in nuclei. The symmetry properties of the polarizability tensor are studied for several crystal structures. It allows to predict the appearance of the purely nuclear reflections. Examples of purely nuclear combined reflections in the Mössbauer diffraction pattern corresponding to the crystals described by the Pnma and P6 3 cm space groups are considered.
