KDy(CO3)2 crystallizes in the monoclinic C2/c space group. K(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(3), and four equivalent O(2) atoms. Dy(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 K(1), one Dy(1), and one C(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent K(1), one Dy(1), and one C(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to one K(1), two equivalent Dy(1), and one C(1) atom.
