Abstract

The zwitterionic title compound, C(12)H(17)NO(3)S, is a reduced Schiff base derived from (S)-N-(2-hy-droxy-benzyl-idene)methio-nine. An intra-molecular inter-action between the N-H and carboxyl-ate groups forms a roughly planar (r.m.s. deviation = 0.1405 Å) five-membered ring containing the H(N), N, Cα, C(carboxyl-ate) and O atoms in a penta-gonal conformation. In the crystal, a supra-molecular triangle-shaped motif is generated by mol-ecules held together by O-H⋯O and N-H⋯O hydrogen bonds.
