摘要
以二甲基甲酰胺(DMF)为溶剂成功合成了水杨醛缩水杨酰肼席夫碱/2-氨基吡啶/锌三元混配配合物晶体,通过测定配合物的红外、元素分析和单晶衍射等物理性质,确定该配合物是一种三核配合物,X射线衍射实验结果表明:标题配合物晶体属于三斜晶系,空间群为P(?),Z=1,分子式为Zn_3(L1)_2(2-NH_2-py)_4·0.5DMF,α=1.15359(9)nm.b= 1.92734(15)nm,c=2.31772(19)nm,α=78.290(2)°,β=78.6930(10)°,γ=88.1090(10)°,V=4.9478(7)nm^3,D_c=1.498 g/cm^3.F(000)=2288,μ(Mo Ka)=1.506mm^(-1),R=0.0449,wR=0.0787.同时在DMF溶液中测定了该Schiff碱及其锌配合物的荧光活性。
The crystal of zinc complex Zn3(L1)2(2-NH2-py)4-0.5DMF with salicylaldehyde salicyloylhydrazone and 2-aminopyridine was obtained in DMF, which is a tri-nuclear complex. It has been characterized by IR, elemental analysis and X-ray diffraction analysis. It crystallizes in the monoclinic system with space group P1^-, Z=1, a=1.15359(9) nm, b=1.92734(15) nm, c=2.31772(19) nm, α=78.290(2)°,β= 78.6930(10)°,γ=88.1090(10)°, V=4.9478(7) nm^3, Dc=1.498 g/cm^3, F(000)=2288, μ(Mo Kα)= 1.506 mm^-1, R=0.0449 and wR=0.0787. The fluorescence activities in DMF of the complex and Schiff base ligand were studied.
