The material structure described by Cu2P3O10 crystallizes in the monoclinic P2_1/m space group. Cu(1) is bonded to one O(1), one O(2), one O(3), one O(4), and one O(5) atom to form distorted CuO5 trigonal bipyramids that share  a cornercorner with one P(3)O4 tetrahedra, corners with two equivalent P(1)O4 tetrahedra, corners with two equivalent P(2)O4 tetrahedra, and  an edgeedge with one Cu(1)O5 trigonal bipyramid. There are three inequivalent P sites. In the first P site, P(1) is bonded to one O(3), one O(6), and two equivalent O(1) atoms to form PO4 tetrahedra that share  a cornercorner with one P(3)O4 tetrahedra and corners with four equivalent Cu(1)O5 trigonal bipyramids. In the second P site, P(2) is bonded to one O(5), one O(7), and two equivalent O(4) atoms to form PO4 tetrahedra that share  a cornercorner with one P(3)O4 tetrahedra and corners with four equivalent Cu(1)O5 trigonal bipyramids. In the third P site, P(3) is bonded to one O(6), one O(7), and two equivalent O(2) atoms to form PO4 tetrahedra that share  a cornercorner with one P(1)O4 tetrahedra,  a cornercorner with one P(2)O4 tetrahedra, and corners with two equivalent Cu(1)O5 trigonal bipyramids. There are seven inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Cu(1) and one P(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Cu(1) and one P(3) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to two equivalent Cu(1) and one P(1) atom. In the fourth O site, O(4) is bonded in a distorted bent 120 degrees geometry to one Cu(1) and one P(2) atom. In the fifth O site, O(5) is bonded in a distorted trigonal planar geometry to two equivalent Cu(1) and one P(2) atom. In the sixth O site, O(6) is bonded in a bent 120 degrees geometry to one P(1) and one P(3) atom. In the seventh O site, O(7) is bonded in a bent 150 degrees geometry to one P(2) and one P(3) atom. is represented by the Crystallographic Information File (CIF) [CIF]
