摘　　要：合成了标题配合物[Ni(en)3]2+H2dsh2- (H4dsh = 1,2-二水杨酰基肼)。晶体属正交晶系, 分子式为C20H34N8NiO4, 空间群为P212121。a = 10.5094(4), b = 12.5003(8), c = 17.487(1) , V = 2297.2(2) 3, Z = 4, Mr = 509.26, Dc = 1.472 g/cm3, = 0.889 mm-1, F(000) = 1080, R = 0.0327, wR = 0.0375。Ni(II)原子由3个乙二胺的6个氮原子形成八面体配位, NiN(en)键键长介于2.110(3)~2.151(2) 拧T诒晏馀浜衔镏?1,2-二水杨酰基肼配体以负二价的阴离子形式存在。[Ni(en)3]2+与H2dsh2-之间通过氢键相连并形成二维网络结构。The title nickel complex with 1,2-disalicyloylhydrazine, [Ni(en)3]2+H2dsh2-, has been synthesized. It crystallizes in orthorhombic, space group P212121 with a = 10.5094(4), b = 12.5003(8), c = 17.487(1) , V = 2297.2(2) 3, Z = 4, Mr = 509.26, Dc = 1.472 g/cm3, = 0.889 mm-1, F(000) = 1080, R = 0.0327 and wR = 0.0375. Six nitrogen atoms of three ethylenediamine ligands in the cation coordinate to the Ni(II) ion, forming a distorted octahedron. The bond distances of Ni(II)N(en) range from 2.110(3) to 2.151(2) ? The neighbor- ing molecules of the title complex are linked by intermolecular NH贩稯 hydrogen bonds between [Ni(en)3]2+ dications and H2dsh2- dianions, forming a two-dimensional network.
