“…10:1, and whilst these are more compatible with the peaks at 624 cm −1 , the calculations indicate that PdF 5 is the least stable of the palladium fluorides and is unstable with respect to disproportionation to PdF 4 and PdF 6 . Whilst PtF 5 is known, 93,94 there do not appear to be any reputable reports for PdF 5 . 1 It is hard to rationalize why PdF 5 should be formed, but not PdF 3 or even PdF 6 .…”

Palladium atoms generated by thermal evaporation and laser ablation were reacted with and trapped in F2/Ar, F2/Ne, and neat F2 matrices. The products were characterized by electronic absorption and infrared spectroscopy, together with relativistic density functional theory calculations as well as coupled cluster calculations. Vibrational modes at 540 and 617 cm(-1) in argon matrices were assigned to molecular PdF and PdF2, and a band at 692 cm(-1) was assigned to molecular PdF4. A band at 624 cm(-1) can be assigned to either PdF3 or PdF6, with the former preferred from experimental considerations. Although calculations might support the latter assignment, our conclusion is that in these detailed experiments there is no convincing evidence for PdF6.

“…[ 13,15,16 ] In contrast, the pentafluorides belonging to the RuF 5 structure type (RuF 5 , OsF 5 , RhF 5 , PtF 5 ), which may be described as corrugated tetramers, have fluorine atoms that pack in a distorted hexagonal close packed array. [ 17–20 ] Additionally, within the MoF 5 structure type, the point symmetry of the M 4 F 20 ( M = Nb, Ta, Mo, W) molecule is C 2 h , with a twofold rotation axis running through both M (1) atoms and the perpendicular mirror plane that bisects the M (2), F(1) and F(2) atoms. In the RuF 5 structure type, the M 4 F 20 ( M = Ru, Os, Rh, Pt) molecule has C i point symmetry.…”

A new synthetic route for the synthesis of WF5 utilizing a mercury photosensitized reduction of tungsten hexafluoride with H2 is described. Crystals of WF5 were studied using single‐crystal X‐ray diffraction, resulting in the first‐reported crystal structure of WF5. Powder X‐ray diffraction studied at room‐temperature showed the compound was phase‐pure. The IR spectrum of WF5 was reinvestigated and interpreted with the use of solid‐state quantum‐chemical calculations using the DFT‐PBE0 density functional method. The compound synthesized herein was free of HF and moisture but may have contained minute amounts of WOF4, that were only observed in the IR spectrum.

A titanium imido complex, ButN=TiClPy2[2‐Me2NCH2‐(C4H3N)] 1, was synthesized through metathesis by reacting ButN=TiCl2Py3 with lithium 2‐(dimethylaminomethyl) pyrrolate (LLi) in diethyl ether at room temperature. The dark brown red crystals were obtained from a concentrated diethyl ether solution of compound 1at −20°C and the monoclinic crystal shows a distorted octahedral structure with two pyridines taking trans positions. Hydrolysis ButN=TiCl2Py3 with 2,2′‐methylene‐bis(6‐t‐butyl‐4‐methylphenol) (HO∼∼CH2∼∼OH)generates a bis phenoxide titanium complex, (O∼∼CH2∼∼O)TiCl2Py 2, by eliminating one equivalent of ButNH2. Similarly, the reaction of LH with PhN=WCl4(OEt2) in diethyl ether at room temperature generates PhN=WCl3(L) 3, in moderate yield. 3has been characterized by NMR spectroscopies and X‐ray crystallography.
