Sr(BS2)2 crystallizes in the trigonal R-3 space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 9-coordinate geometry to three equivalent S(2) and six equivalent S(1) atoms. In the second Sr site, Sr(2) is bonded in an octahedral geometry to six equivalent S(1) atoms. B(1) is bonded in a trigonal planar geometry to one S(1) and two equivalent S(2) atoms. There are two inequivalent S sites. In the first S site, S(1) is bonded to one Sr(2), two equivalent Sr(1), and one B(1) atom to form a mixture of distorted corner and edge-sharing SSr3B tetrahedra. In the second S site, S(2) is bonded in a bent 120 degrees geometry to one Sr(1) and two equivalent B(1) atoms.
Sr(BS2)2 crystallizes in the trigonal R-3 space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 9-coordinate geometry to three equivalent S(2) and six equivalent S(1) atoms. All Sr(1)-S(2) bond lengths are 3.59 Å. There are three shorter (3.17 Å) and three longer (3.19 Å) Sr(1)-S(1) bond lengths. In the second Sr site, Sr(2) is bonded in an octahedral geometry to six equivalent S(1) atoms. All Sr(2)-S(1) bond lengths are 3.04 Å. B(1) is bonded in a trigonal planar geometry to one S(1) and two equivalent S(2) atoms. The B(1)-S(1) bond length is 1.79 Å. Both B(1)-S(2) bond lengths are 1.81 Å. There are two inequivalent S sites.
