摘　　要：A new complex, [Ni3（L）2（BTA）2]·2H2O （1, L = 1,4-di（1H-imidazol-4-yl）benzene, H3BTA = benzene-1,3,5-triacetic acid）, has been hydrothermally prepared and characterized by single-crystal X-ray diffraction, IR spectroscopy, elemental analysis, TG and PXRD. The complex crystallizes in monoclinic, space group P1 with a = 9.0303（12）, b = 10.0796（13）, c = 12.7966（17） A, a = 99.268（2）, β= 94.490（2）, y = 103.722（3）°, V = 1108.5（3） A3, Z = 2, C48HasNsO14Ni3, Mr= 1126.99, Dc = 1.688 g/cm3, p = 1.344 mm1, S = 1.001, F（000） = 578, the final R = 0.0389 and wR = 0.0895 for 3083 observed reflections （I 〉 2σ（I））. In the title complex, the flexible BTA3- ligands utilize oxygen atoms of carboxylate groups to coordinate with Ni（II） ions to form two-dimensional double-layer networks which are further pillared into a three-dimension framework via the rigid ditopic ligand L. Topological analysis revealed that complex 1 is a typical （3,8）-connected tfz-d 3D network based on the trinuclear [Ni3（CO2）6N4] subunits.A new complex, [Ni3（L）2（BTA）2]·2H2O （1, L = 1,4-di（1H-imidazol-4-yl）benzene, H3BTA = benzene-1,3,5-triacetic acid）, has been hydrothermally prepared and characterized by single-crystal X-ray diffraction, IR spectroscopy, elemental analysis, TG and PXRD.
