The title compound, C(6)H(8)NO(3)P, is isostructural with p-arsanilic acid. It exists as the zwitterion H(3)N(+)C(6)H(4)PO(3)H(-). In the crystal, mol-ecules are linked by O-H⋯O and N-H⋯O hydrogen-bond bridges, giving a three-dimensional network structure. The strongest hydrogen bonds are formed between adjacent PO(3)H groups with O⋯O distances of 2.577 (2) Å.
标题化合物C(6)H(8)NO(3)P与对氨基苯胂酸同构。它以两性离子H(3)N(+)C(6)H(4)PO(3)H(-)的形式存在。在晶体中，分子通过O—H⋯O和N—H⋯O氢键桥相连，形成三维网络结构。相邻的PO(3)H基团之间形成最强的氢键，O⋯O距离为2.577 (2) Å。
