KGd(CO3)F2 crystallizes in the orthorhombic Fddd space group. K(1) is bonded in a 8-coordinate geometry to four equivalent O(2) and four equivalent F(1) atoms. Gd(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), and four equivalent F(1) atoms. C(1) is bonded in a trigonal planar geometry to one O(1) and two equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Gd(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 Gd(1), and one C(1) atom. F(1) is bonded in a 4-coordinate geometry to two equivalent K(1) and two equivalent Gd(1) atoms.
