The title acid, C10H7NO2.2H2O, crystallized in the non-centrosymmetric space group Cc with one zwitterionic organic molecule and two water molecules in the asymmetric unit. One N-H...O and four O-H...O hydrogen bonds are present in this structure, with donor-acceptor distances ranging from 2.688 (2) to 2.852 (3) A. These hydrogen bonds generate a three-dimensional network. Structural comparisons are made with anhydrous quinoline-4-carboxylic acid.
标题酸C10H7NO2·2H2O在非中心对称空间群Cc中结晶,不对称单元中有一个两性离子有机分子和两个水分子。该结构中存在一个N-H…O氢键和四个O-H…O氢键,供体-受体距离在2.688(2)至2.852(3)Å之间。这些氢键形成了一个三维网络。与无水喹啉-4-羧酸进行了结构比较。
