چکیده
In the title compound, C(16)H(20)N(2)O(4), the mol-ecule features a zigzag -CH(2)-NH-CH(2)-CH(2)-NH-CH(2)- chain whose ends are connected to the hydroxy-phenyl rings. The mol-ecules lies about a center of inversion. The imino group is a hydrogen-bond donor for the hydr-oxy group, which is a hydrogen-bond donor for the imino group of an adjacent mol-ecule. This latter inter-molecular hydrogen bonding leads to a layer structure.

The title Schiff base, C(21)H(26)N(2)O(2), contains two intra-molecular O-H⋯N hydrogen bonds between the hydroxyl groups and the nearest imine N atoms, each leading to a six-membered ring. Weak C-H⋯O hydrogen bonds result in a ladder network running along the a axis. In addition, inter-molecular C-H⋯π inter-actions serve to stabilize the extended structure.
