4-Ammonio-2,2,6,6-tetra­methyl­piperidinium bis­(dihydrogen phosphate) monohydrate

In the crystal structure of the title compound, C9H22N2 2+·2H2PO4 −·H2O, the H2PO4 − anions are hydrogen bonded to each other, forming a ribbon parallel to the b axis. The water mol­ecules connect these ribbons via O—H⋯O hydrogen bonds. The organic cations are attached to the dihydrogen phosphate anions and water mol­ecules through N—H⋯O and C—H⋯O hydrogen bonds, forming an infinite three-dimensional network

2-Phenyl­anilinium dihydrogen phosphate

In the crystal structure of the title compound, C12H12N+·H2PO4 −, the dihydrogen phosphate anions and the 2-phenyl­anilinium cations are associated via O—H⋯O and N—H⋯O hydrogen bonds so as to build inorganic layers around the x = 1/2 plane. The organic entities are anchored between these layers through C—H⋯O hydrogen bonds, forming a three-dimensional infinite network. The dihedral angle between the aromatic rings is 44.7 (4)°
