Abstract
The title compound, C20H21N3O3.0.75H2O, crystallizes as exceedingly thin fibers. The crystal packing arrangement is related to those of other hydrophobic dipeptides with phenylalanine residues, but the structure has pseudo-tetragonal symmetry in an orthorhombic space group with four peptide molecules and three water molecules in the asymmetric unit.
摘要
标题化合物C20H21N3O3·0.75H2O以极细的纤维形式结晶。晶体堆积排列与其他含有苯丙氨酸残基的疏水二肽的排列有关，但该结构在正交空间群中具有假四方对称性，不对称单元中有四个肽分子和三个水分子。
