利用对二甲氨基苯甲醛和2,4-二硝基苯肼的缩合反应合成了对二甲氨基苯甲醛缩2,4-二硝基苯腙,利用红外、紫外光谱和元素分析进行了结构表征.利用X射线衍射分析方法测定了晶体结构,结果表明化合物中分子为平面型结构,偏离平面的最大的N(2) 原子距平面0.00351(2) nm;分子内和分子间的氢键使晶胞内的分子沿c轴成锯齿型链,分子间有芳环堆积作用存在.

4-Dimethylaminobenzaldehyde 2,4-dinitrophenyl hydrazone was achieved by the condensation of 4-dimethylaminobenzaldehyde with 2,4-dinitrophenylhydrazine. The structure of the title compound wascharacterized by IR, UV and elemental analysis. X-Ray diffraction analysis shows that it has a big planar structure, and the maximum deviation from this planeis 0.00351(2) nm for atom N(2). The inter- and intra-molecular hydrogen bonds jointhe molecules forming a zigzag chain along the c-axis. A π-π* stackinginteraction is found in the crystal.

Key words: 4-dimethylaminobenzaldehyde 2,4-dinitrophenyl hydrazone, synthesis, crystal structure
