Sr3Sc(BO3)3 crystallizes in the trigonal R-3 space group. Sr(1) is bonded in a 9-coordinate geometry to two equivalent O(1), three equivalent O(3), and four equivalent O(2) atoms. There are two inequivalent Sc sites. In the first Sc site, Sc(1) is bonded in an octahedral geometry to six equivalent O(1) atoms. In the second Sc site, Sc(2) is bonded in an octahedral geometry to six equivalent O(3) 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 4-coordinate geometry to two equivalent Sr(1), one Sc(1), and one B(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to four equivalent Sr(1) and one B(1) atom. In the third O site, O(3) is bonded in a 2-coordinate geometry to three equivalent Sr(1), one Sc(2), and one B(1) atom.
