LiSc2Al2(CO)2 crystallizes in the monoclinic C2/m space group. Li(1) is bonded in a distorted square co-planar geometry to two equivalent Sc(1) and two equivalent C(1) atoms. There are two inequivalent Sc sites. In the first Sc site, Sc(1) is bonded in a distorted square co-planar geometry to two equivalent Li(1) and two equivalent C(1) atoms. In the second Sc site, Sc(2) is bonded to six equivalent O(1) atoms to form distorted edge-sharing ScO6 octahedra. Al(1) is bonded in a 4-coordinate geometry to three equivalent C(1) and one O(1) atom. C(1) is bonded in a 5-coordinate geometry to one Li(1), one Sc(1), and three equivalent Al(1) atoms. O(1) is bonded to three equivalent Sc(2) and one Al(1) atom to form a mixture of corner and edge-sharing OSc3Al tetrahedra.
LiSc2Al2(CO)2 crystallizes in the monoclinic C2/m space group. Li(1) is bonded in a distorted square co-planar geometry to two equivalent Sc(1) and two equivalent C(1) atoms. Both Li(1)-Sc(1) bond lengths are 1.86 Å. Both Li(1)-C(1) bond lengths are 1.93 Å. There are two inequivalent Sc sites. In the first Sc site, Sc(1) is bonded in a distorted square co-planar geometry to two equivalent Li(1) and two equivalent C(1) atoms. Both Sc(1)-C(1) bond lengths are 2.43 Å. In the second Sc site, Sc(2) is bonded to six equivalent O(1) atoms to form distorted edge-sharing ScO6 octahedra. There are two shorter (2.11 Å) and four longer (2.27 Å) Sc(2)-O(1) bond lengths. Al(1) is bonded in a 4-coordinate geometry to three equivalent C(1) and one O(1) atom. There is one shorter (2.04 Å) and two longer (2.15 Å) Al(1)-C(1) bond lengths. The Al(1)-O(1) bond length is 1.82 Å. C(1) is bonded in a 5-coordinate geometry to one Li(1), one Sc(1), and three equivalent Al(1) atoms. O(1) is bonded to three equivalent Sc(2) and one Al(1) atom to form a mixture of corner and edge-sharing OSc3Al tetrahedra.
