The title compound was synthesized at room temperature in a mixed acetonitrile / ethanol solution and characterized by elemental analysis, IR and single crystal X-ray diffraction. The results show that the complexes are monoclinic and C2 / c space group with unit cell parameters of a = 17.665 (3) , b = 23.661 (5) , c = 7.473 7 ), V = 3 103.0 (10) 3, Z = 4, D c = 1.599 g / cm 3, μ = 1.02 mm -1, F (000) = 1 520, final deviation factor R = 0.052 3, wR = 0.135 9. The structure shows that the Zn (Ⅱ) complex forms a three-dimensional supramolecular structure with large pores through the ligand bridging and π-π stacking. In addition, the fluorescence properties of this compound were also studied.
