The molecular and crystal structures of 16 N-n-alkyl N,N-dimethylammonioacetic acid bromides with chain lengths between n = 1 and n = 16 have been determined. All compounds from n = 5 to n = 16 form bilayers with interdigitated chains. The even-numbered chains display the chain packing type M2(II). The chain packing of the odd-numbered chain compounds is less regular. The head groups of all compounds
已经确定了链长在n = 1和n = 16之间的16种Nn-烷基N,N-二甲基铵乙酸溴化物的分子和晶体结构。从n = 5到n = 16的所有化合物均形成具有叉指链的双层。偶数链显示链装填类型M2(II)。奇数链化合物的链堆积不太规则。所有化合物的头基均通过静电N + ... Br-相互作用以及OH ... Br-氢键连接。短链的化合物以不同的方式堆积。它们的分子构象取决于晶体堆积。
