The material described by P2O5 is Indium-like structured and crystallizes in the trigonal R3c space group. The structure is zero-dimensional and consists of six trihydroxy phosphite molecules and six O1P3O3 clusters. In each O1P3O3 cluster, P(1) is bonded in a distorted T-shaped geometry to one O(2) and two equivalent O(4) atoms. There are two inequivalent O sites. In the first O site, O(2) is bonded in a distorted T-shaped geometry to three equivalent P(1) atoms. In the second O site, O(4) is bonded in a water-like geometry to two equivalent P(1) atoms. is represented by the CIF card [CIF]
