چکیده
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.

In the crystal of the title compound, C(15)H(23)NO(5)S, mol-ecules are linked through N-H⋯O and O-H⋯O hydrogen-bond inter-actions, resulting in centrosymmetric dimers in which the N-H⋯O inter-actions generate R(2) (2)(12) rings and the O-H⋯O inter-actions generate R(2) (2)(14) rings. Weak inter-molecular C-H⋯O inter-actions are also observed.

The non-symmetric title mol-ecule, C32H34N2O5, is based on a tetra-substituted ethyl-enedi-amine backbone. The mol-ecular structure consists of three hy-droxy-benzyl groups and one 2-hy-droxy-5-methyl-benzaldehyde group bonded to the N atoms of the di-amine unit. The ethyl-enedi-amine skeleton shows a regular extended conformation, while the spatial orientation of the phenol arms is governed by...
