Pr(RhP)2 crystallizes in the tetragonal P4/nmm space group. Pr(1) is bonded in a 16-coordinate geometry to four equivalent Rh(1), four equivalent Rh(2), four equivalent P(1), and four equivalent P(2) atoms. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 8-coordinate geometry to four equivalent Pr(1) and four equivalent P(2) atoms. In the second Rh site, Rh(2) is bonded in a 5-coordinate geometry to four equivalent Pr(1), one P(2), and four 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 four equivalent Pr(1) and four equivalent Rh(2) atoms. In the second P site, P(2) is bonded in a 9-coordinate geometry to four equivalent Pr(1), one Rh(2), and four equivalent Rh(1) atoms.
