The crystal structure described by K2Na3SiP3 crystallizes in the orthorhombic Pnma space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 7-coordinate geometry to two equivalent Si(1), one P(3), two equivalent P(1), and two equivalent P(2) atoms. In the second K site, K(2) is bonded in a 4-coordinate geometry to two equivalent P(3) and three equivalent P(1) atoms. There are three inequivalent Na sites. In the first Na site, Na(1) is bonded in a 7-coordinate geometry to two equivalent Si(1), two equivalent P(3), and three equivalent P(2) atoms. In the second Na site, Na(2) is bonded to one P(1), one P(3), and two equivalent P(2) atoms to form corner-sharing NaP4 tetrahedra. In the third Na site, Na(3) is bonded in a 7-coordinate geometry to two equivalent Si(1), one P(2), two equivalent P(1), and two equivalent P(3) atoms. Si(1) is bonded in a distorted trigonal planar geometry to two equivalent K(1), two equivalent Na(1), two equivalent Na(3), one P(1), one P(2), and one P(3) atom. There are three inequivalent P sites. In the first P site, P(3) is bonded in a 9-coordinate geometry to one K(1), two equivalent K(2), one Na(2), two equivalent Na(1), two equivalent Na(3), and one Si(1) atom. In the second P site, P(1) is bonded in a 9-coordinate geometry to two equivalent K(1), three equivalent K(2), one Na(2), two equivalent Na(3), and one Si(1) atom. In the third P site, P(2) is bonded in a 9-coordinate geometry to two equivalent K(1), one Na(3), two equivalent Na(2), three equivalent Na(1), and one Si(1) atom. is represented by the CIF card [CIF]
