The title ammonium compound ethyl 2‐(4‐aminophenoxy)acetate (C10H13NO3, I) and its crown ether inclusion complex [(C10H14NO3)·(18‐crown‐6)]+[PF6]−, II} (18‐crown‐6=1,4,7,10,13,16‐hexaoxacyclo‐octadecane) were synthesized. The ammonium compound I was determined by 1H NMR, IR and ESI‐MS techiniques. X‐ray crystallography reveals that compound I crystallizes in the triclinic system with space group of
标题铵化合物2-(4-氨基苯氧基)乙酸乙酯(C 10 H 13 NO 3,I)及其冠醚包合配合物[(C 10 H 14 NO 3)·(18-crown-6)] + [ PF 6 ] −,II }(18-crown-6 = 1,4,7,10,13,16-hexaoxacyclo-octadecane)合成。铵化合物I是通过1 H NMR,IR和ESI-MS技术测定的。X射线晶体学揭示了化合物我在三斜晶系结晶,空间群的P在-1,所有原子我除了H以外,它们几乎共面,并且NH ···O氢键导致一维链的形成。转子-定子样化合物II在中心对称的单斜晶系中以P 21 / c的空间群结晶。超分子是通过NH ··O氢键相互作用形成的。测量了化合物II随温度变化的介电常数。
