The compound described by Y2(SeO4)3 crystallizes in the monoclinic C2/c space group. Y(1) is bonded in a 8-coordinate geometry to one O(1), one O(2), one O(4), one O(6), two equivalent O(3), and two equivalent O(5) atoms. There are two inequivalent Se sites. In the first Se site, Se(1) is bonded in a tetrahedral geometry to one O(1), one O(4), one O(5), and one O(6) atom. In the second Se site, Se(2) is bonded in a tetrahedral geometry to two equivalent O(2) and two equivalent O(3) atoms. There are six inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Y(1) and one Se(1) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Y(1) and one Se(2) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to two equivalent Y(1) and one Se(2) atom. In the fourth O site, O(4) is bonded in a distorted bent 150 degrees geometry to one Y(1) and one Se(1) atom. In the fifth O site, O(5) is bonded in a 3-coordinate geometry to two equivalent Y(1) and one Se(1) atom. In the sixth O site, O(6) is bonded in a bent 120 degrees geometry to one Y(1) and one Se(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
