          View of a pair of inversion related, major-component reactant molecules of trans-2-butenoate superimposed on the major product component, (3S,4R)-rel-1-hexene-3,4-dicarboxylate; (b) the identical view with the reactant molecules removed. Reactants have green C atoms and gray H atoms, while product molecules have yellow C atoms and black H atoms. Disorder of the product molecule is not shown, and disorder of the O atoms was not resolved (view from 32-day gamma-ray irradiation; see Cryst. Growth Des. 2021, 21, 663-682; DOI: 10.1021/acs.cgd.0c01466)
