title: Parallel sheet structure in cyclopropane gamma-peptides stabilized by C-H...O hydrogen bonds.
abstract: A three-residue trans-cyclopropane gamma-peptide adopts an infinite parallel sheet structure in the solid state stabilized by intermolecular C-H...O hydrogen bonds, as demonstrated by single crystal X-ray diffraction.
