Rb2Ni3S4 crystallizes in the orthorhombic Fmmm space group. Rb(1) is bonded in a 8-coordinate geometry to eight equivalent S(1) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a square co-planar geometry to four equivalent S(1) atoms. In the second Ni site, Ni(2) is bonded in a square co-planar geometry to four equivalent S(1) atoms. S(1) is bonded in a 3-coordinate geometry to four equivalent Rb(1), one Ni(1), and two equivalent Ni(2) atoms.
Rb2Ni3S4 crystallizes in the orthorhombic Fmmm space group. Rb(1) is bonded in a 8-coordinate geometry to eight equivalent S(1) atoms. There are a spread of Rb(1)-S(1) bond distances ranging from 3.40-3.62 Å. There are two inequivalent Ni sites.
