The structure described by RbLaSiS4 crystallizes in the orthorhombic Pnma space group. Rb(1) is bonded in a 8-coordinate geometry to one S(3), three equivalent S(2), and four equivalent S(1) atoms. La(1) is bonded in a 8-coordinate geometry to one S(2), three equivalent S(3), and four equivalent S(1) atoms. Si(1) is bonded in a tetrahedral geometry to one S(2), one S(3), and two equivalent S(1) atoms. There are three inequivalent S sites. In the first S site, S(1) is bonded in a 5-coordinate geometry to two equivalent Rb(1), two equivalent La(1), and one Si(1) atom. In the second S site, S(2) is bonded to three equivalent Rb(1), one La(1), and one Si(1) atom to form distorted corner-sharing SRb3LaSi trigonal bipyramids. In the third S site, S(3) is bonded in a 5-coordinate geometry to one Rb(1), three equivalent La(1), and one Si(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
