| 摘 要： | The title compound {Zn（NIT4Py）（fum）（HEO）2]·H2O}n, where NIT4Py = 2-（4＇- pyridinyl）-4,4,5,5-tetra-methylimidazoline-looxyl-3-oxide and fum = fumarate, has been prepared and structurally characterized by X-ray diffraction. It crystallizes in triclinic, space group P1^- with a = 6.9533（9）, b = 9.805（1）, c = 15.248（2） A, α= 94.608（2）, β = 92.328（2）, γ = 105.840（2）°, C16H24N3O9Zn, Mr = 467.75, V = 994.8（2） A^3, Z = 2, Dc = 1.562 g/cm^3,μ（MoKα） = 1.289 mm^-1, F（000） = 486, the final R = 0.0243 and wR = 0.0622 for 3505 independent reflections with Rint = 0.0125. The Zn（II） adopts a distorted five-coordinate triangle bipyramidal geometry. The basic framework structure of the complex is a 1-D chain. The intrachain hydrogen bonds are helpful to stabilize the 1-D chain structure. Furthermore, the chains are connected by O-H…O hydrogen bonds to give a 2-D double-layer network.
