The structure described by KMo2P3O13 crystallizes in the monoclinic C2/c space group. K(1) is bonded in a distorted hexagonal planar geometry to two equivalent O(2), two equivalent O(4), and two equivalent O(6) atoms. Mo(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form distorted MoO6 octahedra that share corners with two equivalent P(1)O4 tetrahedra and corners with three equivalent P(2)O4 tetrahedra. There are two inequivalent P sites. In the first P site, P(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form PO4 tetrahedra that share corners with four equivalent Mo(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 39-48°. In the second P site, P(2) is bonded to one O(3), one O(4), one O(6), and one O(7) atom to form PO4 tetrahedra that share corners with three equivalent Mo(1)O6 octahedra and  a cornercorner with one P(2)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 42-52°. There are seven inequivalent O sites. In the first O site, O(7) is bonded in a bent 120 degrees geometry to two equivalent P(2) atoms. In the second O site, O(1) is bonded in a bent 150 degrees geometry to one Mo(1) and one P(1) atom. In the third O site, O(2) is bonded in a 3-coordinate geometry to one K(1), one Mo(1), and one P(1) atom. In the fourth O site, O(3) is bonded in a distorted bent 150 degrees geometry to one Mo(1) and one P(2) atom. In the fifth O site, O(4) is bonded in a distorted single-bond geometry to one K(1), one Mo(1), and one P(2) atom. In the sixth O site, O(5) is bonded in a single-bond geometry to one Mo(1) atom. In the seventh O site, O(6) is bonded in a 3-coordinate geometry to one K(1), one Mo(1), and one P(2) atom. is represented by the CIF card [CIF]
