title: N-Z-Pro-D-Leu using synchrotron radiation data from a very small crystal.
abstract: The crystal structure of the neuroactive artificial dipeptide N-benzyloxycarbonylprolyl-D-leucine, C(19)H(26)N(2)O(5), was solved using synchrotron radiation data collected on a very small crystal (20 x 20 x 380 microm). The molecules form hydrogen-bonded 2(1) helices. The acid carbonyl group does not participate in strong hydrogen bonds. This is interpreted as a consequence of close-packing requirements.
