## Abstract The crystal structure and conformation of the synthetic cyclic tetrapeptide, __cyclo__(L‐Pro‐Sar)~2~, was determined by x‐ray analysis. The peptide crystallizes in the orthorhombic space group __P__2~1~2~1~2~1~ with cell parameters __a__ = 9.277(1), __b__ = 12.884(1), and __c__ = 15.581
