77Se and 87Rb Solid state NMR study of the structure of Rb2[Pd(Se4)2].Se8

The structure of Rb(2)Pd(Se(4))(2)].Se(8) has been investigated using (87)Rb magic angle spinning and static NMR and (77)Se magic angle spinning NMR. The number and the integrated intensities of the (87)Rb and (77)Se resonances are in full agreement with the crystallographic structure of the compound. The (87)Rb and (77)Se nuclear spin interaction parameters have been used to characterize the main structural units of the compound: infinite Rb(Se(8))](x)(x+) columns and polymeric Pd(Se(4))(2)](x)(2x-) sheet anions.
