title: Diisopropyl-ammonium hydrogen phenyl-phospho-nate.
abstract: In the title salt, [(CH(3))(2)CH](2)NH(2)](+)·[C(6)H(5)PO(2)(OH)](-), the anions are linked by pairs of O-H⋯O hydrogen bonds, forming inversion dimers. These dimers are bridged by the cations via N-H⋯O hydrogen bonds, leading to a three-dimensional structure.
