C4P2H12O3 is Indium-like structured and crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of four dimethylphosphinic anhydride molecules. There are two inequivalent C sites. In the first C site, C(2) is bonded to one P(1), one H(4), one H(5), and one H(6) atom to form distorted corner-sharing CPH3 tetrahedra. In the second C site, C(1) is bonded to one P(1), one H(1), one H(2), and one H(3) atom to form distorted corner-sharing CPH3 tetrahedra. P(1) is bonded to one C(1), one C(2), one O(1), and one O(2) atom to form distorted corner-sharing PC2O2 tetrahedra. There are six inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one C(1) atom. In the third H site, H(3) is bonded in a single-bond geometry to one C(1) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one C(2) atom. In the fifth H site, H(5) is bonded in a single-bond geometry to one C(2) atom. In the sixth H site, H(6) is bonded in a single-bond geometry to one C(2) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to two equivalent P(1) atoms. In the second O site, O(2) is bonded in a single-bond geometry to one P(1) atom.
