Abstract
In the title compound, C4H12O4P2, there are two crystallographically independent half-molecules in the asymmetric unit, both molecules lying on centres of symmetry. Each molecule is connected on both sides to neighbouring molecules via strong O—H...O hydrogen bonds. The –POOH groups accept and donate one hydrogen bond in interactions with the neighbouring –POOH group of the adjacent molecule, to give one-dimensional chains along [10overline{1}]. As each phosphinic acid group donates and accepts one hydrogen bond, the connection between the molecules is best described by a ring motif which can be classified by the Etter symbol R22(8).
