Y(BO2)6 crystallizes in the trigonal R3c space group. Y(1) is bonded in a 9-coordinate geometry to three equivalent O(1), three equivalent O(2), and three equivalent O(3) atoms. There are two inequivalent B sites. In the first B site, B(1) is bonded in a trigonal planar geometry to one O(1), one O(3), and one O(4) atom. In the second B site, B(2) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(3), and one O(4) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate geometry to one Y(1), one B(1), and one B(2) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one Y(1) and one B(2) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one Y(1), one B(1), and one B(2) atom. In the fourth O site, O(4) is bonded in a bent 120 degrees geometry to one B(1) and one B(2) atom.
