Y(O4Cl)3 crystallizes in the hexagonal P6_3/m space group. Y(1) is bonded in a 9-coordinate geometry to three equivalent O(3) and six equivalent O(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Y(1) and one Cl(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to one Cl(1) atom. In the third O site, O(3) is bonded in a distorted bent 150 degrees geometry to one Y(1) and one Cl(1) atom. Cl(1) is bonded in a tetrahedral geometry to one O(2), one O(3), and two equivalent O(1) atoms.
