摘要

In the structure of (6R*,11R*)-5-acetyl-11-ethyl-6,11-dihydro-5H-dibenzo[b,e]azepine-6-carboxylic acid, C19H19NO3, (I), the molecules are linked into sheets by a combination of O—H...O and C—H...O hydrogen bonds; in the structure of the monomethyl analogue (6RS,11SR)-5-acetyl-11-ethyl-2-methyl-6,11-dihydro-5H-dibenzo[b,e]azepine-6-carboxylic acid, C20H21NO3, (II), the molecules are linked into simple C(7) chains by O—H...O hydrogen bonds; and in the structure of the dimethyl analogue (6RS,11SR)-5-acetyl-11-ethyl-1,3-dimethyl-6,11-dihydro-5H-dibenzo[b,e]azepine-6-carboxylic acid, C21H23NO3, (III), a combination of O—H...O, C—H...O and C—H...π(arene) hydrogen bonds links the molecules into a three-dimensional framework structure. None of these structures exhibits the R22(8) dimer motif characteristic of simple carboxylic acids.

O氢键连接成简单的C(7)链;且在二甲基类似物(6RS,11SR)-5-乙酰基-11-乙基-1,3-二甲基-6,11-二氢-5H-二苯并[b,e] a庚因-6-羧酸C21H23NO3的结构中,(III),OH-O,CH-O和CH-π(芳烃)氢键的组合将分子连接成三维骨架结构。这些结构均未显示出简单羧酸的R22(8)二聚体基序特征。
