NaY(CO3)F2 crystallizes in the orthorhombic Pnma space group. Na(1) is bonded in a 7-coordinate geometry to one O(1), two equivalent O(2), and four equivalent F(1) atoms. Y(1) is bonded in a 8-coordinate geometry to one O(1), one O(2), two equivalent O(3), and four equivalent F(1) 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 T-shaped geometry to one Na(1), one Y(1), and one C(1) atom. In the second O site, O(2) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Na(1), one Y(1), and one C(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to two equivalent Y(1) and one C(1) atom. F(1) is bonded in a rectangular see-saw-like geometry to two equivalent Na(1) and two equivalent Y(1) atoms.
