Despite the extra functional group in the serine side chain, the crystal packing arrangement of the title compound {systematic name: (S)-3-hydroxy-2-[(S)-pyrrolidine-2-carboxamido]propanoic acid monohydrate}, C8H14N2O4·H2O, is essentially the same as observed for a series of L-Pro-L-Nop peptide hydrates, where Nop is a strictly nonpolar residue. This is rendered possible by a monoclinicP21packing arrangement withZ′ = 2 that deviates from orthorhombicP212121symmetry only for the seryl hydroxy groups, which form infinite O—H...O—H hydrogen-bonded chains along the 5.3 Åaaxis. At the same time, cocrystallized water molecules form parallel water wires.

The crystal structure of 2-methyl-2-(2,4,5-trichlorophenoxy)propionic acid was determined. C10H9Cl3O3, Mv 283.5, triclinic, P1, a 9.859(2), b 11.542(2), c 6.247(1) �, α(100.13(2), β 97.26(2), γ 114.68(2)�, pc 1.52 g cm-3, Z 2, F(000) 288, μ (CuKα) 66.1 cm-1. It was solved by direct methods and refined to a final R of 0.051 for 1249 observed reflections. The molecules of the acid form the usual hydrogen bonded cyclic dimers [O. . .O,2.638(5) �] and have the synplanar-synplanar (carbonyl) side-chain conformation common to the phenoxyacetic acids and 2-phenoxypropionic acids but different from previous determinations of phenoxyisobutyric acid analogues.
