The structure described by Ag2P2H2O7 crystallizes in the orthorhombic Fddd space group. Ag(1) is bonded to one O(2), two equivalent O(3), and three equivalent O(4) atoms to form distorted AgO6 octahedra that share corners with six equivalent P(1)O4 tetrahedra and edges with four equivalent Ag(1)O6 octahedra. P(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form PO4 tetrahedra that share corners with six equivalent Ag(1)O6 octahedra and  a cornercorner with one P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 51-61°. There are two inequivalent H sites. In the first H site, H(1) is bonded in a linear geometry to two equivalent O(2) atoms. In the second H site, H(2) is bonded in a linear geometry to two equivalent O(3) atoms. There are four 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 distorted bent 120 degrees geometry to one Ag(1), one P(1), and one H(1) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to two equivalent Ag(1), one P(1), and one H(2) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to three equivalent Ag(1) and one P(1) atom. is represented by the CIF file [CIF]
