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P1, Z=1, 分子式为Zn3(L1)2(2-NH2-py)4•0.5DMF, 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) nm3, Dc=1.498 g/cm3. F(000)=2288, μ(Mo Kα)=1.506 mm-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 salicylal-dehyde 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 mono-clinic 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) nm3, Dc1.498 g/cm3, 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.
