What the study found
The study found previously unobserved cationic adducts, [MF3(XeF2)3]+, where M is platinum or palladium and XeF2 is xenon difluoride. These complexes are mononuclear and contain multiple XeF2 ligands bound to a single metal(IV) center.
Why the authors say this matters
The authors conclude that these cations extend the chemistry of XeF2–MF4 systems. They also say the findings represent rare, crystallographically characterized examples of XeF2 coordination to Pt(IV) and Pd(IV), and the first examples of a new class of XeF2 coordination compounds involving fluoridometal cations.
What the researchers tested
The researchers prepared double salts, [Xe2F3][MF3(XeF2)3][AsF6]2, from anhydrous hydrogen fluoride solutions. They then used low-temperature single-crystal X-ray diffraction, Raman spectroscopy, and quantum-chemical calculations to examine structure, bonding, and electronic structure.
What worked and what didn't
The crystal structures revealed the [MF3(XeF2)3]+ adduct cations for M = Pd and Pt. The quantum-chemical calculations gave optimized gas-phase geometries that agreed well with the experimental solid-state structures.
What to keep in mind
The abstract does not describe experimental limitations or drawbacks. The findings are based on the specific compounds studied here and on solid-state structural characterization.
Key points
