What the study found
The study found previously unobserved [MF3(XeF2)3]+ adduct cations in crystals of two double salts, where M is palladium (Pd) or platinum (Pt). These cations are described as mononuclear, cationic, and coordinated to multiple xenon difluoride (XeF2) ligands.
Why the authors say this matters
The authors say these cations extend the chemistry of XeF2–MF4 systems and represent rare, crystallographically characterized examples of XeF2 coordination to PtIV and PdIV. They also state that the findings define a new class of XeF2 coordination compounds, which could further expand the coordination chemistry of noble-gas fluorides.
What the researchers tested
The calculations included optimized gas-phase geometries, which were compared with the experimental solid-state structures.
What worked and what didn't
The crystal structures showed the [MF3(XeF2)3]+ adduct cations, and the calculated gas-phase geometries agreed well with the experimental solid-state structures. The abstract does not report any failed tests or negative results.
What to keep in mind
The summary only describes two compounds, with M limited to Pd and Pt. The abstract does not give detailed quantitative results or discuss experimental limitations beyond the methods used.
Key points
- Two double salts, [Xe2F3][MF3(XeF2)3][AsF6]2, were studied with M = Pd or Pt.
- Low-temperature single-crystal X-ray diffraction and Raman spectroscopy were used to characterize the crystals.
- The crystals contain previously unobserved [MF3(XeF2)3]+ adduct cations.
- Quantum-chemical calculations showed good agreement with the experimental solid-state structures.
- The authors describe these as rare examples of XeF2 coordination to PtIV and PdIV.
