The open chain crown ether： 2,6-bis （8＇-quinoylyloxymethyl）pyridine was synthesized and the title complex： [-Zn（C25 H19 N3O2 ） H2 07 （NO3）2 was obtained by the reaction of the 2,6-his （8＇- quinoylyloxymethyl）pyridine with Zn（NO3）2. The title complex wes characterized by the melting point determination, IR and the the X-ray diffraction analysis. The title complex belongs to monoclinic system, the space group P2（1）/c. Unit cell dimension： a = 8. 364 0（19）A.b =37. 083（8） A.c = 7. 978 8 （18）A,β = 98. 704（9） 91. 350（3）°, V =2 474.0（10）A3, Z = 4, Dealed=1. 613 Mg/m^3, F（000） = I 232, R1= 0.0573, wR2= 0.1494, R1= 0.0720, wR2=0.157 7. The title complex is madeupofa [-Zn（C25H19N3） H2O-]^2＋ complex cation and two NO3 anions, for the complex cation, the Zn is in the six-coordinated ZnO3N3 coordination environment with the distorted octahedral geometry. For balance charge, the NO3^- ions are observed in the complex. And furthermore, the NO3 are interacted to the [-Zn（C25 H19N3）H2O]2＋ by the O-H…O H-bonds, which may be important to stabilizing the complex.
