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-Hâ¯O hydrogen bond is observed between the alcohol and aldehyde functions, and the neighbouring phenol arm participates in an intra-molecular S(6) O-Hâ¯N hydrogen bond. The third phenol group is involved in a bifurcated intra-molecular hydrogen bond with graph-set notation S(6) for O-Hâ¯N and O-Hâ¯O intra-molecular hydrogen bonds between neighbouring amine and phenol arms, respectively. Finally, the fourth phenol group acts as an acceptor in a bifurcated intra-molecular hydrogen bond and also acts as donor in an inter-molecular hydrogen bond, which connects inversion-related mol-ecules into dimers with R 4 (4)(8) ring motifs.
