SmC2 crystallizes in the tetragonal I4/mmm space group. Sm(1) is bonded in a distorted q4 geometry to ten equivalent C(1) atoms. C(1) is bonded in a 6-coordinate geometry to five equivalent Sm(1) and one C(1) atom.
SmC2 crystallizes in the tetragonal I4/mmm space group. Sm(1) is bonded in a distorted q4 geometry to ten equivalent C(1) atoms. There are two shorter (2.53 Å) and eight longer (2.75 Å) Sm(1)-C(1) bond lengths. C(1) is bonded in a 6-coordinate geometry to five equivalent Sm(1) and one C(1) atom. The C(1)-C(1) bond length is 1.29 Å.
