摘要

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 = 1 3. 844 (12) (A) ,β = 119. 554 (7) °, V = 2677.8 (5) (A)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)(A),α = 106. 436(2) ,β= 104. 531 (2) ,γ =97. 1600( 10)o, V=2975.4(6)(A)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 I exbibits an emission at 606 nm.%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)(A),β=119.554(7)°,V=2677.8(5)(A)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.的72(12),b=16.6211(18),c=17.155(2)(A),α=106.436(2),β=104.531(2),γ=97.1600(10)°,V=2975.4(6)(A)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.
