Rb2Pd(S4O13)2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Rb1+ is bonded in a 10-coordinate geometry to ten O2- atoms. There are a spread of Rb–O bond distances ranging from 3.03–3.42 Å. Pd2+ is bonded in a square co-planar geometry to four O2- atoms. There are two shorter (2.04 Å) and two longer (2.07 Å) Pd–O bond lengths. There are four inequivalent S6+ sites. In the first S6+ site, S6+ is bonded to four O2- atoms to form corner-sharing SO4 tetrahedra. There are a spread of S–O bond distances ranging from 1.43–1.75 Å. In the second S6+ site, S6+ is bonded to four O2- atoms to form corner-sharing SO4 tetrahedra. There are a spread of S–O bond distances ranging from 1.42–1.65 Å. In the third S6+ site, S6+ is bonded to four O2- atoms to form corner-sharing SO4 tetrahedra. There are a spread of S–O bond distances ranging from 1.43–1.81 Å. In the fourth S6+ site, S6+ is bonded to four O2- atoms to form corner-sharing SO4 tetrahedra. There are a spread of S–O bond distances ranging from 1.43–1.65 Å. There are thirteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one Rb1+ and one S6+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one Rb1+ and one S6+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to two S6+ atoms. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to one Pd2+ and one S6+ atom. In the fifth O2- site, O2- is bonded in a single-bond geometry to two equivalent Rb1+ and one S6+ atom. In the sixth O2- site, O2- is bonded in a bent 120 degrees geometry to two S6+ atoms. In the seventh O2- site, O2- is bonded in a single-bond geometry to one Rb1+ and one S6+ atom. In the eighth O2- site, O2- is bonded in a distorted single-bond geometry to one Rb1+ and one S6+ atom. In the ninth O2- site, O2- is bonded in a single-bond geometry to one Rb1+ and one S6+ atom. In the tenth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Pd2+ and one S6+ atom. In the eleventh O2- site, O2- is bonded in a bent 120 degrees geometry to two S6+ atoms. In the twelfth O2- site, O2- is bonded in a single-bond geometry to one Rb1+ and one S6+ atom. In the thirteenth O2- site, O2- is bonded in a single-bond geometry to two equivalent Rb1+ and one S6+ atom.
