摘要: The asymmetric unit of the title compound, (C5H11NO2SC5H12NO2S+.C6H2N3O7-)-C-., is composed two crystallographically independent methionine residues and a picrate anion. protonated methioninium are bonded through strong O-(HO)-O-... hydrogen bond, an inversion-related DL1 head-to-tail sequence along axis observed in zwitterion. amino groups connect to lone oxygen anions. Hydrophobic layers y = 0 plane.
