• Resumen

  • The asymmetric unit of the title compound C11H16N,05 , 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 N02 groups, probably gives a more stable crystal structure. The molecule represents a precursor of a polyaza macrocylic ligands.
