KY(CO3)4 crystallizes in the tetragonal I4_1/a space group. K(1) is bonded in a 4-coordinate geometry to four equivalent O(1) and four equivalent O(3) atoms. Y(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. C(1) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(2) atom. There are three inequivalent O sites. In the first O site, O(2) is bonded in a bent 120 degrees geometry to one Y(1) and one C(1) atom. In the second O site, O(3) is bonded in a single-bond geometry to one K(1) atom. In the third O site, O(1) is bonded in a distorted trigonal planar geometry to one K(1), one Y(1), and one C(1) atom.
