The structure described by Cs5SiP3 crystallizes in the orthorhombic Pnma space group. There are five inequivalent Cs sites. In the first Cs site, Cs(1) is bonded in a 3-coordinate geometry to one P(2) and two equivalent P(1) atoms. In the second Cs site, Cs(2) is bonded in a 4-coordinate geometry to one P(2) and three equivalent P(3) atoms. In the third Cs site, Cs(3) is bonded in a 3-coordinate geometry to one P(2) and two equivalent P(1) atoms. In the fourth Cs site, Cs(4) is bonded in a 5-coordinate geometry to two equivalent P(2) and three equivalent P(3) atoms. In the fifth Cs site, Cs(5) is bonded in a 4-coordinate geometry to one P(1), one P(3), and two equivalent P(2) atoms. Si(1) is bonded in a trigonal planar geometry to one P(1), one P(2), and one P(3) atom. There are three inequivalent P sites. In the first P site, P(1) is bonded in a 1-coordinate geometry to one Cs(5), two equivalent Cs(1), two equivalent Cs(3), and one Si(1) atom. In the second P site, P(2) is bonded in a 1-coordinate geometry to one Cs(1), one Cs(2), one Cs(3), two equivalent Cs(4), two equivalent Cs(5), and one Si(1) atom. In the third P site, P(3) is bonded in a 1-coordinate geometry to one Cs(5), three equivalent Cs(2), three equivalent Cs(4), and one Si(1) atom. is represented by the CIF file [CIF]
