Based on theoretical considerations, it is shown that deviations of the structure of small particles from the Bragg approximation on an infinite crystal lattice leads to significant differences in the diffraction patterns, which may lead to an erroneous interpretation of the experimental results. An alternative evaluation of the diffraction data of nano-particles, based on the so-called ``apparent lattice parameter'', alp, is proposed. Based on this method, it is shown that real nano-crystals constitute a complex, heterogeneous multi-phase structure.
