The partiallyfluorinated oxo-alkoxide tungsten(VI) complexes WO(OR)4 [4; R = C(CH3)2CF3, 5; R = C(CH3)(CF3)2] have been synthesized as precursors for chemical vapour deposition (CVD) of WOx nanocrystalline material. Complexes 4 and 5 were prepared by salt metathesis between sodium salts of the fluoroalkoxides and WOCl4. Crystallographic structure analysis allows comparison of the bonding in 4 and

Single‐Molecule Magnets: A Combined Terahertz, Far‐IR and Vibronic Barrier Model Study
Fluorination at the axial position of pentagonal-bipyraimdal dysprosium(III) single-moleculemagnets is shown to effectively reduce the anharmonic phonon-assisted Raman relaxation process, as validated by THz, far-IR, ab initio, and DFT calculations using a newly established vibronic-barrier model.
