The material described by K4Cd(P3O10)2 crystallizes in the triclinic P-1 space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 9-coordinate geometry to one O(1), one O(2), one O(6), one O(7), one O(8), two equivalent O(3), and two equivalent O(4) atoms. In the second K site, K(2) is bonded in a 7-coordinate geometry to one O(10), one O(2), one O(4), two equivalent O(5), and two equivalent O(6) atoms. Cd(1) is bonded to two equivalent O(1), two equivalent O(10), and two equivalent O(5) atoms to form CdO6 octahedra that share corners with two equivalent P(1)O4 tetrahedra and corners with two equivalent P(3)O4 tetrahedra. There are three inequivalent P sites. In the first P site, P(1) is bonded to one O(1), one O(2), one O(7), and one O(9) atom to form PO4 tetrahedra that share  a cornercorner with one Cd(1)O6 octahedra,  a cornercorner with one P(2)O4 tetrahedra, and  a cornercorner with one P(3)O4 tetrahedra. The corner-sharing octahedral tilt angles are 43°. In the second P site, P(2) is bonded to one O(3), one O(4), one O(7), and one O(8) atom to form corner-sharing PO4 tetrahedra.

The corner-sharing octahedral tilt angles are 56°. There are ten inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate geometry to one K(1), one Cd(1), and one P(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one K(1), one K(2), and one P(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to two equivalent K(1) and one P(2) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to one K(2), two equivalent K(1), and one P(2) atom. In the fifth O site, O(5) is bonded in a 1-coordinate geometry to two equivalent K(2), one Cd(1), and one P(3) atom. In the sixth O site, O(6) is bonded in a distorted single-bond geometry to one K(1), two equivalent K(2), and one P(3) atom. In the seventh O site, O(7) is bonded in a 2-coordinate geometry to one K(1), one P(1), and one P(2) atom. In the eighth O site, O(8) is bonded in a distorted bent 120 degrees geometry to one K(1), one P(2), and one P(3) atom. In the ninth O site, O(9) is bonded in a bent 120 degrees geometry to one P(1) and one P(3) atom. In the tenth O site, O(10) is bonded in a water-like geometry to one K(2) and one Cd(1) atom. is represented by the CIF file [CIF]
