Davies SG., Siddall E., Thompson AL., Thomson JE.
Crystals of the tripeptide Cbz-[(1R,2S)-ACPC]3-OH 4, derived from the β-amino acid (1R,2S)-2-aminocyclopentanecarboxylic acid, were synthesised and studied by X-ray diffraction. Tripeptide 4 crystallizes in the orthorhombic space group P 2 1 2 1 2 1 with cell parameters of a = 7.8957(1) Å, b = 12.9289(2) Å, c = 24.7850(4) Å, V = 2530.12(6) Å3 and Z = 4. Adjacent molecules are linked by a series of N-H···O=C and O- H···O=C hydrogen bonds to form a double tape-like arrangement.
