苦味酸盐的合成与晶体结构研究

Synthesis and Crystal Structure of a Salt of Picric Acid

亚胺N(CH2CH2N=CH-C6H3-2,4-(OH)2)3与苦味酸镧在DMF中反应,得到了一个苦味酸盐[N(CH2CH2NH3)3][C6H2-O-2,4,6-(NO2)3]3.H2O.用X-射线单晶衍射法测定了这个化合物的晶体结构.通过晶体结构的研究发现晶体中存在多重氢键作用和芳环的π-π相互作用.

A novel salt of picric acid [N（CH2CH2NH3）3][C6H2-O-2,4,6-（NO2）3]3 · H2O, is synthesized by using N（CH2CH2N=CH-C6H3-2,4- （OH）2）3 and La[C6H2-O-2,4,6- （NO2）3]3.Its structure is determined by X-ray analysis and numerous H-bonding and π-π stacking interactions are found in the crystal lattice.
