Abstract
The crystal structure of l-methionyl-l-alanine, C8H16N2O3S, is very similar to that of l-valyl-l-alanine [Görbitz & Gundersen (1996). Acta Cryst. C52, 1764–1767] and other related dipeptides in space group P61, but there are seven molecules in the asymmetric unit. The Z value of 42 is the highest ever observed for a chiral molecule.
