The crystal structure of Feist's acid, 1-methylenecyclopropane-trans-2,3-dicarboxylic acid, has been examined. The substance crystallizes in the triclinic system with space group [...]. Two enantiomorphous molecules of formula [...] are in the unit cell; the direct-cell constants are [...] and [...]. There is good cleavage at the face (010), and this is also the twinning plane.
The intensity data from equi-inclination Weissenberg photographs about each crystal axis were utilized in selecting and then refining a trial structure. Punched-card computing techniques were used to carry out least-squares refinements of atomic positions; two Fourier summations aided in final refinement. All refining work was based on full three-dimensional data.
Hydrogen bonds bind individual molecules into chains which extend in the [...] direction through the crystal. The methylene groups extended in the [...] direction form cogs on the chains, and two chains related by centers of symmetry are intermeshed closely.
