The material structure described by RbSm(CO3)2 crystallizes in the monoclinic C2/c space group. Rb(1) is bonded in a 6-coordinate geometry to two equivalent O(3) and four equivalent O(2) atoms. Sm(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), and four equivalent O(3) atoms. C(1) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(3) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear geometry to one Sm(1) and one C(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Rb(1), one Sm(1), and one C(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to one Rb(1), two equivalent Sm(1), and one C(1) atom. is represented by the CIF card [CIF]
