The crystal structure described by U6Rh20P13 crystallizes in the trigonal P-3 space group. U(1) is bonded in a 16-coordinate geometry to one Rh(4), two equivalent Rh(1), three equivalent Rh(2), four equivalent Rh(3), two equivalent P(2), and four equivalent P(1) atoms. There are four inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 9-coordinate geometry to six equivalent U(1) and three equivalent P(1) atoms. In the second Rh site, Rh(2) is bonded in a 12-coordinate geometry to three equivalent U(1), two equivalent Rh(3), three equivalent Rh(4), one P(1), and three equivalent P(2) atoms. In the third Rh site, Rh(3) is bonded in a 12-coordinate geometry to four equivalent U(1), two equivalent Rh(2), two equivalent Rh(3), one P(2), and three equivalent P(1) atoms. In the fourth Rh site, Rh(4) is bonded in a 4-coordinate geometry to one U(1), three equivalent Rh(2), one P(3), and three equivalent P(2) atoms. There are three inequivalent P sites. In the first P site, P(1) is bonded in a 9-coordinate geometry to four equivalent U(1), one Rh(1), one Rh(2), and three equivalent Rh(3) atoms. In the second P site, P(2) is bonded in a 9-coordinate geometry to two equivalent U(1), one Rh(3), three equivalent Rh(2), and three equivalent Rh(4) atoms. In the third P site, P(3) is bonded in a distorted octahedral geometry to six equivalent Rh(4) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
