摘要
Five organic compounds were selected and their structures were determined by Xray diffraction. It was found that the disordered arrangement (occupying rate, position) existing in the partial atoms under the crystal state leads to the exchange in the molecular conformation, and by means of X-ray diffraction analysis, the average molecular structures are obtained. The disorder phenomena in the organic crystal structures exist universally, which make it more difficult to determine the crystal structures correctly in three-dimensional space.
