We report on the X-ray powder diffraction and magnetic measurements of the polycrystalline and the two nanocrystalline samples of DyMnO_{3} compound synthesized at temperatures of 800 and 850°C. All samples at room temperature crystallize in the orthorhombic crystal structure (space group Pnma). The crystal structure parameters determined change only slightly with preparation methods but the average grains size of the nanoparticles determined from X-ray data increases significantly with increasing annealing temperature. Temperature dependence of the magnetic susceptibility indicates the antiferromagnetic order in Dy sublattice at low temperatures.
