Rh2BiP crystallizes in the trigonal R3m space group. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 7-coordinate geometry to one Rh(2), three equivalent Bi(1), and three equivalent P(1) atoms. The Rh(1)-Rh(2) bond length is 2.63 Å. All Rh(1)-Bi(1) bond lengths are 2.70 Å. All Rh(1)-P(1) bond lengths are 2.70 Å. In the second Rh site, Rh(2) is bonded in a distorted single-bond geometry to one Rh(1), three equivalent Bi(1), and one P(1) atom. All Rh(2)-Bi(1) bond lengths are 2.70 Å. The Rh(2)-P(1) bond length is 1.65 Å. Bi(1) is bonded in a 10-coordinate geometry to three equivalent Rh(1), three equivalent Rh(2), and four equivalent P(1) atoms. There is one shorter (2.63 Å) and three longer (2.86 Å) Bi(1)-P(1) bond lengths. P(1) is bonded in a distorted single-bond geometry to one Rh(2), three equivalent Rh(1), and four equivalent Bi(1) atoms.
