摘　　要：利用水热法合成2种吡啶-2-甲醛缩水杨酰腙配合物[Zn(C13H10N3O2)2].H2O(1)和[Ni(C13H11N3O2)2]2(CH3CH2OH)(SO4)2.3H2O(2),并测定了晶体结构。结果表明1属单斜晶系,空间群P21/c,其晶胞参数为:a=12.4352(14),b=17.878(2),c=13.844(12),β=119.554(7)°,V=2677.8(5)3,其中配体以三齿脱质子形式存在,和Zn2+离子螯合,形成稍变形八面体构型。2属三斜晶系,空间群Pī,其晶胞参数为:a=11.4972(12),b=16.6211(18),c=17.155(2),α=106.436(2),β=104.531(2),γ=97.1600(10)°,V=2975.4(6)3,其中Ni2+离子是六配位的稍变形八面体构型。1展示了荧光性能。Two complexes [Zn（C13H10N3O2）2]·H2O（1） and [Ni（C13H11N3O2）2]2（CH3CH2OH）-（SO4）2·3H2O（2） with pyridine-2-aldehyde salicylhydrazone have been synthesized by hydrothermal method and structurally characterized.Complex 1 belongs to monoclinic with space group P21/c,cell parameters：a=12.4352（14）,b=17.878（2）,c=13.844（12）,β=119.554（7）°,V=2677.8（5）3.The Ni2＋ ion is six coordinated by two O atoms and four N atoms of two deprotonated trichelating ligand to give a distorted octahedron.Complex 2 belongs to triclinic with space group P ī,cell parameters：a=11.4972（12）,b=16.6211（18）,c=17.155（2）,α=106.436（2）,β=104.531（2）,γ=97.1600（10）o,V=2975.4（6）3.The Ni2＋ ion is six coordinated by two O atoms and four N atoms of two trichelating ligand to form a distorted octahedron.Photoluminescent studies have shown that complex 1 exhibits an emission at 606 nm.
