Abstract: The structure of 4-isobutyl-1,3-oxazolidine-2,5-dione, C7H11NO3, has been determined to explain the polymerization of a series of amino acid N-carboxy anhydrides in the solid state. A dimer structure is formed between the L- and D-enantiomers around a crystallographic centre of symmetry via N-H
O hydrogen bonds. The five-membered rings are arranged in a layer, sandwiched between two layers of isopropyl groups. This structure should be conducive to the polymerization of the compound in the solid state.
