PrRhC2 crystallizes in the orthorhombic Amm2 space group. Pr(1) is bonded in a 14-coordinate geometry to six equivalent Rh(1) and eight equivalent C(1) atoms. Rh(1) is bonded in a 4-coordinate geometry to six equivalent Pr(1) and four equivalent C(1) atoms. C(1) is bonded in a 7-coordinate geometry to four equivalent Pr(1), two equivalent Rh(1), and one C(1) atom.
PrRhC2 crystallizes in the orthorhombic Amm2 space group. Pr(1) is bonded in a 14-coordinate geometry to six equivalent Rh(1) and eight equivalent C(1) atoms. All Pr(1)-Rh(1) bond lengths are 3.14 Å. There are four shorter (2.83 Å) and four longer (2.89 Å) Pr(1)-C(1) bond lengths. Rh(1) is bonded in a 4-coordinate geometry to six equivalent Pr(1) and four equivalent C(1) atoms. There are two shorter (2.11 Å) and two longer (2.17 Å) Rh(1)-C(1) bond lengths. C(1) is bonded in a 7-coordinate geometry to four equivalent Pr(1), two equivalent Rh(1), and one C(1) atom. The C(1)-C(1) bond length is 1.35 Å.
