RbPbPS4 crystallizes in the orthorhombic P2_12_12_1 space group. Rb(1) is bonded in a 8-coordinate geometry to one S(1), two equivalent S(2), two equivalent S(3), and three equivalent S(4) atoms. Pb(1) is bonded in a 6-coordinate geometry to one S(2), one S(4), two equivalent S(1), and two equivalent S(3) atoms. P(1) is bonded in a tetrahedral geometry to one S(1), one S(2), one S(3), and one S(4) atom. There are four inequivalent S sites. In the first S site, S(1) is bonded in a 4-coordinate geometry to one Rb(1), two equivalent Pb(1), and one P(1) atom. In the second S site, S(2) is bonded in a distorted single-bond geometry to two equivalent Rb(1), one Pb(1), and one P(1) atom. In the third S site, S(3) is bonded in a distorted single-bond geometry to two equivalent Rb(1), two equivalent Pb(1), and one P(1) atom. In the fourth S site, S(4) is bonded in a distorted single-bond geometry to three equivalent Rb(1), one Pb(1), and one P(1) atom.
