biostudies-literatureUnknown70(Pt 5)Nikawa YIn the crystal structure of the title compound, C5H14NO4P·H2O, the zwitterionic phospho-choline mol-ecules are connected by an O-H⋯O hydrogen bond between the phosphate groups, forming a zigzag chain along the b-axis direction. The chains are further connected through O-H⋯O hydrogen bonds involving water mol-ecules, forming a layer parallel to (101). Three and one C-H⋯O inter-actions are also observed in the layer and between the layers, respectively. The conformation of the N-C-C-O backbone is gauche with a torsion angle of -75.8 (2)°Acta crystallographica.
