The crystal structures of the four‐membered heterocycles ( S )‐(−)‐4‐oxo‐2‐azetidinecarboxylic acid (I) and 3‐azetidinecarboxylic acid (II) were solved by direct methods using powder synchrotron X‐ray diffraction data. The asymmetry of the oxoazetidine and azetidine rings is discussed, along with the hydrogen bonding.
