Crystal structure of 3-[({2-[bis­(2-hy­droxy­benz­yl)amino]­eth­yl}(2-hy­droxy­benz­yl)amino)­meth­yl]-2-hydroxy-5-methyl­benzaldehyde

The mol­ecular structure of a non-symmetric structure based on a tetra­substituted ethyl­enedi­amine backbone consists of three hy­droxy­benzyl groups and one 2-hy­droxy-5-methyl­benzaldehyde group bonded to the N atoms of the di­amine unit. The ethyl­enedi­amine skeleton shows a regular extended conformation, while the phenol arms are randomly oriented but governed by hydrogen bonds.
