The reaction of 3-ethoxysalicylaldehyde-N,N-bis (3-aminopropyl)methylamine with Zn (Ⅱ) acetate in CH3CH2OH followed by recrystallization in CH3CH2OH gave rise to colourless block crystals of 3-ethoxysalicylaldehyde-N,N-bis(3-aminopropyl)methylamine Zn(Ⅱ). The compound has been characterized by elemental analysis,IR spectrum, molar conductivity and X-ray diffraction structure determination single crystal. It crystallizes in monoclinic, space group P21/c with a=1.028 91(13) nm, b=1.400 35(12) nm, c=1.733 69(19) nm, V=2.476 6(5) nm3, Z=4, Mr=504.91, Dc= 1.354 g. cm-3, T=298(2) K, F(000)= 1 064,μ(Mo Kα)=0.102 7 cm-1, R =0.068 4 and wR =0.185 3for 2 940 observed reflections with I＞2σ(Ⅰ). The fluorescence properties of ligand and the complex also have been investigated. The results show that the fluorescence intensity of the Zn(Ⅱ) complex is very stronger than the ligand. In the crystal, the molecules form 1D chain structure by π-π stacking. CCDC: 675010.
