title: Ammonium hydrogen (RS)-[(5-methyl-2-oxo-1,3-oxazolidin-3-yl)meth-yl]phospho-nate.
abstract: In the title compound, NH(4) (+)·C(5)H(9)NO(5)P(-), the five-membered methyl-oxazolidin-2-one unit is disordered over two positions, the major component having a site occupancy of 0.832 (9). A three-dimensional network of O-H⋯O and N-H⋯O hydrogen bonds stabilizes the crystal structure.
