Sr6YSc(BO3)6 crystallizes in the trigonal R-3 space group. Sr(1) is bonded in a 8-coordinate geometry to two equivalent O(2), three equivalent O(1), and three equivalent O(3) atoms. Y(1) is bonded in an octahedral geometry to six equivalent O(2) atoms. Sc(1) is bonded in an octahedral geometry to six equivalent O(1) atoms. B(1) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(3) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate geometry to three equivalent Sr(1), one Sc(1), and one B(1) atom. In the second O site, O(2) is bonded in a 1-coordinate geometry to two equivalent Sr(1), one Y(1), and one B(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to three equivalent Sr(1) and one B(1) atom.
