Crystal structure of 3-[({2-[bis-(2-hy-droxy-benz-yl)amino]-eth-yl}(2-hy-droxy-benz-yl)amino)-meth-yl]-2-hydroxy-5-methyl-benzaldehyde.

ABSTRACT: 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 hydrogen bonds. In the 2-hy-droxy-5-methyl-benzaldehyde group, an intra-molecular S(6) O-H⋯O hydrogen bond is observed between the alcohol and aldehyde functions, and the neighbouring phenol arm participates in an intra-molecular S(6) O-H⋯N hydrogen bond. The third phenol group is involved in a bifurcated intra-molecular hydrogen bond with graph-set notation S(6) for O-H⋯N and O-H⋯O intra-molecular
