摘　　要：A novel 2D layered compound （H4HMTA）2（H3O）2{Na2（H2O）6（H2W12O42） }C12-11H2O （HMTA = hexamethylenetetraamine） has been synthesized and characterized by elemental analyses, IR, UV-Vis and X-ray diffraction. C12H74CI2N8Na2O61W12 （Mr = 3629.87） crystallizes in the triclinic system, space group P1 with a = 10.5518（2）, b = 12.1837（2）, c = 14.3088（2） A, α = 112.9470（10）, β = 93.1310（10）, γ= 106.1530（10）°, V = 1599.20（5）A3 Dc = 3.769 g.cm^-3, Z = 1, μ（MoKα） = 21.705 mm^-1, F（000） = 1634, the final R = 0.0287 and wR = 0.0686 for 5846 observed reflections with I 〉 2σ（I）. The 2D layered network is assembled from paradodecatungstate clusters linked by simple sodium-oxo bridging groups. The compound exhibits electrocatalytic activities toward both reduction and oxidation of nitrite.A novel 2D layered compound （H4HMTA）2（H3O）2{Na2（H2O）6（H2W12O42） }C12-11H2O （HMTA = hexamethylenetetraamine） has been synthesized and characterized by elemental analyses, IR, UV-Vis and X-ray diffraction.
