N2 - The synthesis, crystal structures, chemical and spectroscopic properties of NaPdPS4, RbPdPS4, and RbPdPS4{Rb 0.33P0.4S2.23Ox} are described. NaPdPS4, RbPdPS4, are isostructural and crystallize in the tetragonal system I4/mcm with cell parameters a=7.3074(8)Å, c=12.2308(14)Å and a=8.2954(3)Å, c=12.2284(4)Å respectively. RbPdPS4{Rb0.33P0.4S2.23O x} is cubic, space group Pm-3n and a=12.0042(2)Å. All compounds contain the same 1∞[PdPS4]- chains made of alternating square planar Pd2+ cations and tetrahedral [PS 4]3- anions. RbPdPS4{Rb0.33P 0.4S2.23Ox} contains co-crystallized highly disordered molecular species encapsulated within [Rb8] cubic cavities. Spectroscopic solid state 31P NMR, infrared and Raman data as well as elemental analysis suggest that these species could be S n2- (n=3 or 4) anions and possibly cationic [P 4S6O]6+ fragments. NaPdPS4 and RbPdPS4 exhibit exfoliative dissolution in polar solvents giving rise to solutions that show signs of complex fluid behavior.
