Sr(BS2)2 crystallizes in the monoclinic P2_1/c space group. Sr(1) is bonded in a 9-coordinate geometry to two equivalent S(2), two equivalent S(3), two equivalent S(4), and three equivalent S(1) atoms. There are two inequivalent B sites. In the first B site, B(1) is bonded to one S(3), one S(4), and two equivalent S(1) atoms to form a mixture of edge and corner-sharing BS4 tetrahedra. In the second B site, B(2) is bonded to one S(3), one S(4), and two equivalent S(2) atoms to form corner-sharing BS4 tetrahedra. There are four inequivalent S sites. In the first S site, S(1) is bonded in a 5-coordinate geometry to three equivalent Sr(1) and two equivalent B(1) atoms. In the second S site, S(2) is bonded in a 4-coordinate geometry to two equivalent Sr(1) and two equivalent B(2) atoms. In the third S site, S(3) is bonded in a 4-coordinate geometry to two equivalent Sr(1), one B(1), and one B(2) atom. In the fourth S site, S(4) is bonded in a 2-coordinate geometry to two equivalent Sr(1), one B(1), and one B(2) atom.
