Origins of the bond distance anomalies observed for the X-ray structures of a series of organic compounds are discussed in terms of molecular motion and reactions in crystals. The unusual shortening of the central bond in stilbene-type compounds has been ascribed to an artifact originated from molecular motion in crystals. The anomalous elongation of the central C - C bond in bi (anthracene-9, 10-dimethylene) photoisomer has been ascribed to an artifact originated from a cycloreversion reaction in crystals.
