The least-coordinating anion [(R<sup>F</sup>O)<sub>3</sub>Al–F–Al(OR<sup>F</sup>)<sub>3</sub>]<sup>−</sup> and its more Lewis-basic brother [F–Al(OR<sup>F</sup>)<sub>3</sub>]<sup>−</sup> (R<sup>F</sup> = C(CF<sub>3</sub>)<sub>3</sub>).
Homoleptic carbonyl radical cations are a textbook family of complexes hitherto unknown in the condensed phase, leaving their properties and applications fundamentally unexplored. Here we report on two stable 17-electron [Cr(CO)6]•+ salts that were synthesized by oxidation Cr(CO)6 with [NO]+[Al(ORF)4]- (RF = C(CF3)3)) CH2Cl2 removal NO gas. Longer reaction times led to NO/CO ligand exchange formation thermodynamically more 18-electron species [Cr(CO)5(NO)]+, which belongs heteroleptic...

The oxidation chemistry of a range Au I ‐bis(NHC) (NHC = N‐heterocyclic carbene) complexes with hypervalent iodine(III) oxidants has been explored. precursors have synthesised by treatment the corresponding [Au(NHC)Cl] derivatives imidazol(idin)ium salts in presence K 2 CO 3 . reactivity towards PhICl revealed an influence nature NHC ligands present complex on outcome reaction: small and more strongly electron‐donating favoured formation III species. On basis these results, bearing two...
The oxidation of Fe(CO)5 with the [NO]+ salt weakly coordinating perfluoroalkoxyaluminate anion [F-{Al(ORF )3 }2 ]- (RF =C(CF3 ) leads to stable salts 18 valence electron (VE) species [Fe(CO)4 (NO)]+ and [Fe(CO)(NO)3 ]+ Enemark-Feltham numbers {FeNO}8 {FeNO}10 . This finally concludes triad heteroleptic iron carbonyl/nitrosyl complexes, since first discovery anionic ([Fe(CO)3 (NO)]- neutral ([Fe(CO)2 (NO)2 ]) over 80 years ago. Both complexes were fully characterized (IR, Raman, NMR, UV/Vis,...
The syntheses of the two novel complexes [Ag{Mo/W(CO)
Abstract Although similar to carbon monoxide, the chemistry of homoleptic nitrogen monoxide complexes is fundamentally unexplored compared their carbonyl analogues. Herein we report synthesis first truly transition‐metal nitrosyl cation as salt weakly coordinating anions (WCAs) [Al(OR F ) 4 ] − and [F{Al(OR 3 } 2 (R =C(CF ). These salts are easily accessible in good yields, phase pure, were fully characterized by IR/Raman, NMR UV/Vis spectroscopy well single‐crystal powder X‐ray diffraction....
Lithium ion conductivity in haloaluminate solid electrolytes can be tuned by the softening of anion sublattice via a judicious juggling migration activation energy, E and Meyer–Neldel Δ 0 .
Abstract Die Oxidation von Fe(CO) 5 mit dem [NO] + ‐Salz des schwach koordinierenden Perfluoroalkoxyaluminat‐Anions [F‐{Al(OR F ) 3 } 2 ] − (R =C(CF führt zu stabilen Salzen der 18‐Valenzelektronenspezies [Fe(CO) 4 (NO)] und [Fe(CO)(NO) den Enemark‐Feltham‐Zahlen {FeNO} 8 10 . Dies schließt 80 Jahre nach Entdeckung anionischen ([Fe(CO) )‐ neutralen (NO) ])‐Spezies endlich die bisherige Lücke in Triade heteroleptischen Eisen‐Carbonyl/Nitrosylkomplexe. Beide Salze wurden vollständig...
Abstract Trotz der Ähnlichkeit zu Kohlenmonoxid ist die Chemie von homoleptischen Stickstoffmonoxidkomplexen im Unterschied ihren Carbonylanaloga bislang grundlegend unerforscht. Hier beschreiben wir Synthese des ersten echten Übergangsmetallnitrosylkomplexes als Salz schwach koordinierenden Anionen (WCAs) [Al(OR F ) 4 ] − und [F{Al(OR 3 } 2 (R =C(CF ). Diese Salze sind in guten Ausbeuten phasenrein zugänglich wurden vollständig durch IR/Raman‐, NMR‐ UV/Vis‐Spektroskopie sowie mittels...
