Crystals of glucyl-DL-phenylalanine are orthorhombic, space Pbca, with a=9.241(2), b=28.41(1), and c=8.602(2) Å. The structure has been solved by the symbolic addtion method and refined to an R index of 0.041 for 2271 reflections. The peptide group is non-planner, the torsion angle about the peptide bond being -170.2(2)° for tge L molecules. The strecture is stabilized by a network of intermolecualr hydregen bonds N-H…O; there is also evidence for the presence of C-H…O interactions.
