1, 3-二（4-羟基-N‘-亚甲基苯并酰肼）苯的合成与晶体结构
Synthesis and Crystal Structure of 1, 3-bis (4-hydroxy-N’-methylenebenzohydrazide) benzene
一种新型的席夫碱，1, 3-二（4-羟基-N’-亚甲基苯并酰肼）苯（H4L）通过一步合成法合成，对它进行了元素分析、红外光谱的表征，并用X射线衍射测定了它的单晶结构。H4L属于单斜晶系，P2(1)/c空间群，晶胞参数：a =15.189(3) ?, b = 7.5123(12) ?, c = 19.945(4) ?。晶体结构表明：共轭的H4L以独立的分子存在，其依靠分子间的氢键作用来构筑超分子结构。

A novel Schiff base, 1, 3-bis (4-hydroxy-N‘-methylenebenzohydrazide) benzene (H4L), was synthesized via a one-pot process and characterized by means of elemental analysis, FT-IR and single crystal X-ray crystallography. It crystallizes in the monoclinic system, space group P2(1)/c with a =15.189(3) ?, b = 7.5123(12) ?, c = 19.945(4) ?. The crystal structure shows that the conjugate H4L exists as a discrete molecule and hydrogen bonding exists in the H4L to construct supramolecular architecture.
