In the title compound, C(4)H(12)O(4)P(2), there are two crystallographically independent half-mol-ecules in the asymmetric unit, both molecules lying on centres of symmetry. Each mol-ecule is connected on both sides to neighbouring mol-ecules 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 mol-ecule, to give one-dimensional chains along [10]. As each phosphinic acid group donates and accepts one hydrogen bond, the connection between the mol-ecules is best described by a ring motif which can be classified by the Etter symbol R(2) (2)(8).
在标题化合物C₄H₁₂O₄P₂中，不对称单元中有两个晶体学独立的半分子，两个分子均位于对称中心上。每个分子通过强O—H⋯O氢键在两侧与相邻分子相连。-POOH基团在与相邻分子的相邻-POOH基团的相互作用中接受和提供一个氢键，从而沿[10]方向形成一维链。由于每个次膦酸基团提供和接受一个氢键，分子之间的连接最好用一个环基序来描述，该环基序可以用 Etter 符号R₂²(8)进行分类。
