YC2 crystallizes in the tetragonal I4/mmm space group. Y(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 Y(1) and one C(1) atom.
YC2 crystallizes in the tetragonal I4/mmm space group. Y(1) is bonded in a distorted q4 geometry to ten equivalent C(1) atoms. There are two shorter (2.45 Å) and eight longer (2.68 Å) Y(1)-C(1) bond lengths. C(1) is bonded in a 6-coordinate geometry to five equivalent Y(1) and one C(1) atom. The C(1)-C(1) bond length is 1.30 Å.
