A novel Schiff base macrocyclic compound 1 has been synthesized from resorcin and diethylenetriamine by condensation and cyclizaction. The single crystal X-ray structural analysis reveals that it crystallizes in monoclinic system, with space group P21/c, a＝0.81977(9) nm, b＝1.27817(14) nm, c＝1.60193(17) nm, α＝90°, β＝93.34(3)°, γ＝90°, V＝1.6757(3) nm3, Z＝4, R1＝0.0553 and wR2＝0.1603. Four ionic hydrogen bonds were observed in the macrocyclic compound. The macrocyclic compound has a quadrilat-eral framework, and a strong intramolecular π-π interaction exists between the two parallel benzene rings.
