Sr3(BS3)2 crystallizes in the monoclinic C2/c space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 8-coordinate geometry to two equivalent S(2), three equivalent S(1), and three equivalent S(3) atoms. In the second Sr site, Sr(2) is bonded in a 8-coordinate geometry to two equivalent S(1), two equivalent S(3), and four equivalent S(2) atoms. B(1) is bonded in a trigonal planar geometry to one S(1), one S(2), and one S(3) atom. There are three inequivalent S sites. In the first S site, S(1) is bonded in a distorted single-bond geometry to one Sr(2), three equivalent Sr(1), and one B(1) atom. In the second S site, S(2) is bonded in a 5-coordinate geometry to two equivalent Sr(1), two equivalent Sr(2), and one B(1) atom. In the third S site, S(3) is bonded in a 5-coordinate geometry to one Sr(2), three equivalent Sr(1), and one B(1) atom.
