  Spectroscopic studies on the hexafluoroanions of platinum(V) and rhodium(V)

  摘要：

  IR and UV-vis spectra are reported for the unstable K[RhF6] and K[PtF6] salts. Assignment of the UV-vis spectra on the basis of the strong-field model and optical-electronegativity approach allows chi(opt)M(V) to be calculated for the first time for rhodium and platinum as 3.1 and 3.25, respectively.

  Intercalation of rhodium fluoride into graphite: Reaction mechanism in anhydrous HF and physical characterization

  摘要：

  The intercalation process of rhodium fluoride into graphite has been investigated using anhydrous liquid HF. Evidence of a two-step mechanism has been given by XRD. A cointercalation of HF2- and of rhodium fluorospecies is confirmed by both XRD and XPS. The final stage depends on the type of pristine graphite: a stage-2 compound of average composition C28RhF3.3 (HF2) 1.3 and I(c) = 11.25 angstrom is obtained from HOPG, whereas stage-1 compounds wih I(c) = 7.87 angstrom are formed with natural flaky samples. During the dissolution and intercalation processes, pentavalent rhodium is reduced to diamagnetic trivalent species. An excellent agreement is achieved between the experimental EXAFS spectrum of rhodium fluoride-GIC and calculations based on a regular octahedral environment of rhodium (with 6 Rh-F at 1.99 angstrom), similar to that of RhF3.

  Single-crystal structure determinations of all nine transition metal hexafluorides (Mo, Tc, Ru, Rh, W, Re, Os, Ir, and Pt) at -140 degrees C are presented. All compounds crystallize alike and have the same molecular structure. The bond length sequence r(w-F) congruent with r(Re-F) congruent with r(Os-F) < r(Ir-F) < r(Pt-F) is confirmed and paralleled by the sequence r(Mo-F) congruent with r(Tc-F) congruent

  Abstract Charge transfer has been evaluated in stage-2 CxCrFy and CxRhFy GIC's by optical measurements. Charge transfer coefficients f = 0.50 and f = 0.59 per intercalated species have been determined from reflectivity data using the Blinowski-Rigaux model. The corresponding contractions of in-plane C-C bond lengths ( δ C-C = 4×10 −3 A and 3.3×10 −3 A 2 respectively) have been deduced. The shift of

  and RhF6 are reported involving fluorination of the corresponding pentafluorides at 220 °C and 30 atm. Infra-red spectra for RuF6 and RhF6 isolated in nitrogen and argon matrices at 12 K have been recorded and assigned. The u.v.–visible spectra in nitrogen matrices are complex containing both fluorine-to-metal charge-transfer and d–d transitions. Assignments for the main features are proposed.
