Resumen

The asymmetric unit of the title compound C17H16N4O5, contains one molecule of the compound (L3)(1,3-bis(2-nitrobenzylideneamino)propan-2-ol). The molecule shows a chiral C atom but the absolute structure was not possible to be determined by X-ray diffraction. The molecule shows intermolecular hydrogen bonding involving the hydroxy group and an imine nitrogen atom of a symmetry related molecule. The molecular distribution shows weak interactions between oxygen atoms of the nitro groups and two different C-H groups of benzene rings. The extended weak H bond formation, using the NO2 groups, probably gives a more stable crystal structure. The molecule represents a precursor of a polyaza macrocyclic ligands.
