The title compound, C 4 H 11 NO 6 P 2 , reveals a two‐dimensional network of P—O—H⋯O=P and N—H⋯O=P hydrogen‐bond interactions, forming molecular slabs parallel with the (010) plane. One O—H⋯O interaction is distinct within these sets: whilst forming the shortest intermolecular hydrogen bond, it possesses a short P—O(H) bond of 1.5291 (10) Å. Weak C—H⋯O contacts link individual stacks to produce a three‐dimensional array. The compound is zwitterionic: one H atom from a P—O—H group has transferred to the pyrrolidine ring N atom.
