K2P3 crystallizes in the orthorhombic Fmmm space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 8-coordinate geometry to four equivalent P(1) and four equivalent P(2) atoms. In the second K site, K(2) is bonded in a 10-coordinate geometry to two equivalent P(2) and eight equivalent P(1) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded in a 8-coordinate geometry to two equivalent K(1), four equivalent K(2), one P(1), and one P(2) atom. In the second P site, P(2) is bonded in a 8-coordinate geometry to two equivalent K(2), four equivalent K(1), and two equivalent P(1) atoms.
K2P3 crystallizes in the orthorhombic Fmmm space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 8-coordinate geometry to four equivalent P(1) and four equivalent P(2) atoms. All K(1)-P(1) bond lengths are 3.43 Å. All K(1)-P(2) bond lengths are 3.47 Å. In the second K site, K(2) is bonded in a 10-coordinate geometry to two equivalent P(2) and eight equivalent P(1) atoms. Both K(2)-P(2) bond lengths are 3.34 Å. There are four shorter (3.34 Å) and four longer (3.41 Å) K(2)-P(1) bond lengths. There are two inequivalent P sites. In the first P site, P(1) is bonded in a 8-coordinate geometry to two equivalent K(1), four equivalent K(2), one P(1), and one P(2) atom. The P(1)-P(1) bond length is 2.15 Å. The P(1)-P(2) bond length is 2.15 Å. In the second P site, P(2) is bonded in a 8-coordinate geometry to two equivalent K(2), four equivalent K(1), and two equivalent P(1) atoms.
