is composed of two crystallographically independent methionine residues and a picrate anion. The methionine and protonated methioninium residues are bonded through a strong O-HÁ Á ÁO hydrogen bond, and an inversion-related dl1 head-to-tail sequence along the a axis is observed in the zwitterion. The
