The material structure described by PtP2O7 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded to two equivalent O(5), two equivalent O(6), and two equivalent O(7) atoms to form PtO6 octahedra that share corners with two equivalent P(2)O4 tetrahedra and corners with four equivalent P(1)O4 tetrahedra. In the second Pt site, Pt(2) is bonded to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms to form PtO6 octahedra that share corners with two equivalent P(1)O4 tetrahedra and corners with four equivalent P(2)O4 tetrahedra. There are two inequivalent P sites. In the first P site, P(1) is bonded to one O(1), one O(4), one O(5), and one O(6) atom to form PO4 tetrahedra that share  a cornercorner with one Pt(2)O6 octahedra, corners with two equivalent Pt(1)O6 octahedra, and  a cornercorner with one P(2)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 44-51°. In the second P site, P(2) is bonded to one O(1), one O(2), one O(3), and one O(7) atom to form PO4 tetrahedra that share  a cornercorner with one Pt(1)O6 octahedra, corners with two equivalent Pt(2)O6 octahedra, and  a cornercorner with one P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 49-51°. There are seven inequivalent O sites. In the first O site, O(6) is bonded in a distorted bent 150 degrees geometry to one Pt(1) and one P(1) atom. In the second O site, O(7) is bonded in a distorted bent 120 degrees geometry to one Pt(1) and one P(2) atom. In the third O site, O(1) is bonded in a bent 120 degrees geometry to one P(1) and one P(2) atom. In the fourth O site, O(2) is bonded in a distorted bent 120 degrees geometry to one Pt(2) and one P(2) atom. In the fifth O site, O(3) is bonded in a distorted bent 120 degrees geometry to one Pt(2) and one P(2) atom. In the sixth O site, O(4) is bonded in a bent 120 degrees geometry to one Pt(2) and one P(1) atom. In the seventh O site, O(5) is bonded in a distorted bent 120 degrees geometry to one Pt(1) and one P(1) atom. is represented by the CIF card [CIF]
