SmRhC2 crystallizes in the orthorhombic Amm2 space group. Sm(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 Sm(1) and four equivalent C(1) atoms. C(1) is bonded in a 7-coordinate geometry to four equivalent Sm(1), two equivalent Rh(1), and one C(1) atom.
SmRhC2 crystallizes in the orthorhombic Amm2 space group. Sm(1) is bonded in a 14-coordinate geometry to six equivalent Rh(1) and eight equivalent C(1) atoms. There are two shorter (3.08 Å) and four longer (3.09 Å) Sm(1)-Rh(1) bond lengths. There are four shorter (2.77 Å) and four longer (2.84 Å) Sm(1)-C(1) bond lengths. Rh(1) is bonded in a 4-coordinate geometry to six equivalent Sm(1) and four equivalent C(1) atoms. There are two shorter (2.10 Å) and two longer (2.16 Å) Rh(1)-C(1) bond lengths. C(1) is bonded in a 7-coordinate geometry to four equivalent Sm(1), two equivalent Rh(1), and one C(1) atom. The C(1)-C(1) bond length is 1.35 Å.
