Sc(CO2)3 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Sc sites. In the first Sc site, Sc(1) is bonded in an octahedral geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. In the second Sc site, Sc(2) is bonded in an octahedral geometry to two equivalent O(4), two equivalent O(5), and two equivalent O(6) atoms. There are three inequivalent C sites. In the first C site, C(1) is bonded in a bent 120 degrees geometry to one O(1) and one O(3) atom. In the second C site, C(2) is bonded in a bent 120 degrees geometry to one O(2) and one O(4) atom. In the third C site, C(3) is bonded in a bent 120 degrees geometry to one O(5) and one O(6) atom. There are six inequivalent O sites. In the first O site, O(5) is bonded in a bent 150 degrees geometry to one Sc(2) and one C(3) atom. In the second O site, O(6) is bonded in a bent 150 degrees geometry to one Sc(2) and one C(3) atom.
