RbBS3 crystallizes in the monoclinic P2_1/c space group. Rb(1) is bonded in a 10-coordinate geometry to three equivalent S(1), three equivalent S(3), and four equivalent S(2) atoms. B(1) is bonded to one S(1), one S(2), and two equivalent S(3) atoms to form corner-sharing BS4 tetrahedra. There are three inequivalent S sites. In the first S site, S(1) is bonded in a distorted single-bond geometry to three equivalent Rb(1) and one B(1) atom. In the second S site, S(2) is bonded in a distorted single-bond geometry to four equivalent Rb(1) and one B(1) atom. In the third S site, S(3) is bonded in a distorted water-like geometry to three equivalent Rb(1) and two equivalent B(1) atoms.
RbBS3 crystallizes in the monoclinic P2_1/c space group. Rb(1) is bonded in a 10-coordinate geometry to three equivalent S(1), three equivalent S(3), and four equivalent S(2) atoms. There are a spread of Rb(1)-S(1) bond distances ranging from 3.52-3.67 Å. There are a spread of Rb(1)-S(3) bond distances ranging from 3.41-3.62 Å. There are a spread of Rb(1)-S(2) bond distances ranging from 3.48-3.82 Å. B(1) is bonded to one S(1), one S(2), and two equivalent S(3) atoms to form corner-sharing BS4 tetrahedra.
