| Popis: |
The complex [H3NCH2CH2NH3][PdBr6] has been isolated as well-formed brown crystals. The Raman (single crystal) and FTIR (wax disc) spectra of the complex have been recorded but the band assignments are complicated by extensive factor group splitting and resonance effects. The crystal belongs to space group Pnnm, with Z = 2, each ion occupying sites of 2/m (C2h) symmetry. The [PdBr6]2− ion is very close to octahedral, the two unique PdBr distances, 2.466(3) and 2.470(3) A, being equal within experimental error and the BrPdBr angles being 90 ± 0.8°. The diammonium cation has an extended, planar, trans structure. |
