Fig. 6: Crystal structure of the heterochiral coiled-coil-like 11.
From: The folding propensity of α/sulfono-γ-AA peptidic foldamers with both left- and right-handedness
a Single-crystal structures of left-handed helix d-15-mer 9 and right-handed helix l-15-mer 8. b The crystal structures and crystal packing of heterochiral coiled-coil formed by racemic 15-mer 11. c Representative intermolecular interactions in the racemic crystals of 11. The intermolecular C = O···H‒Ph and C‒H···H‒Ph interactions are indicated as cyan and yellow dashed line, respectively. The interhelical C‒H···Cl‒Ph interactions are shown as red dashed line. Solvent molecules were excluded from the crystal lattice.
