In the second B site, B(2) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form corner-sharing BO4 tetrahedra. In the third B site, B(3) is bonded to one O(4), one O(5), and two equivalent O(6) atoms to form corner-sharing BO4 tetrahedra. There are six inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to one B(2) and two equivalent B(1) atoms. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one Y(1), one B(1), and one B(2) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one B(1) and one B(2) atom. In the fourth O site, O(4) is bonded in a distorted bent 120 degrees geometry to one Y(1), one B(2), and one B(3) atom. In the fifth O site, O(5) is bonded in a distorted single-bond geometry to three equivalent Y(1) and one B(3) atom. In the sixth O site, O(6) is bonded in a distorted bent 120 degrees geometry to one Y(1) and two equivalent B(3) atoms.
