Estimating the Wavenumber of Terminal Metal-Hydride Stretching Vibrations of Octahedral d6 Transition Metal Complexes

“…We gathered together terminal metal-hydride and metal-deuteride vibration wavenumbers of d 6 octahedral metal complexes of groups 7, 8, 9, and 10 found scattered in the literature. ,− …”

Synthesis, Structure, and Electrochemistry of Osmametallocenophanes with Different Ring Size,1

“…Os 3 (CO) 12 , Na 2 [Os(CO) 4 ], Re 2 (CO) 10 , FeCl 2 (THF) 1.44 , the 2- {[ ω-(1,3-cyclopentadien-1-yl)alkyl]oxy}tetrahydro-2 H -pyrans 1a − c , and tetrabutylammonium hexafluorophosphate were synthesized according to literature methods.…”

GC-MS exploration of photochemically generated species of Os, W and Ru from reductive and oxidative media

“…Based on the known generation of Fe(CO) 5 during photolysis of Fe 2/3+ in a formic acid medium, 21 it was speculated that a volatile compound of the form Os w (CO) x (CH 3 ) y H z may be generated in acetic acid, as opposed to a simpler Os(CO) 5 or clustered polynuclear complex 41 [such as Os 3 (CO) 12 ] that may arise in formic acid due not only to the very low concentrations used for PVG synthesis, but because Os(CO) 5 only slowly converts to the triosmium cluster at temperatures above 80 °C. 42 Moreover, we a priori presume here that a likely methylated Os species is actually generated as it is well-known that the CO ligands are generally quite labile in transition metal carbonyls, 43–45 particularly under UV irradiation, 46 and given the ready availability of H˙ and H 3 C˙ radicals in the photolysed acetic acid medium, 1,3 possible formation of a generalized species such as Os w (CO) x (CH 3 ) y H z should not be overlooked. The inability to detect Os species by GC-MS as a volatile PVG product is likely connected with the reactivity of such carbonylated metal species.…”
