Reaction of vanadium(V) oxide trifluoride (VOF3) and the new "naked" fluoride reagent [(LDipp)H][F] (LDipp = 1,3-bis(2,6-diisopropylphenyl)-1,3-dihydro-2 H-imidazol-2-ylidene) leads to the isolation of [(LDipp)H][VOF4] (1) where the long sought discrete [VOF4]- anion was finally obtained. The neutral [(LDipp)VOF3] (2) complex was synthesized by a similar reaction between VOF3 and bulky N-heterocyclic carbene (NHC) ligand LDipp. In this context, we analyzed, by means of DFT calculations…

Four new complexes, namely, Cu2(O-cpia)(btb)0.5·(OH) (1), Cu3(O-cpia)2(bpy)2 (2), [Ni2(O-cpia)(phen)·(OH)·H2O]·2H2O (3) and [Ni3(O-cpia)2(bpy)3·2H2O]·2H2O (4) (O-cpia =

Coordination of a Neutral Ligand to a Metal Center of Oxohalido Anions: Fact or Fiction?

The current study shows that relying solely on the structural aspects of solved crystal structures, such as ligand orientation and bond distances, can lead to the wrong interpretation of the chemical bonding.



Complexes of Vanadium(V) oxide trifluoride with nitrogen and oxygen donor ligands: Coordination chemistry and some fluorination reactions

[VOF3(MeCN)], obtained by dissolving VOF3 in dry acetonitrile, is a useful synthon for the preparation of complexes of the oxide-fluoride, and the reaction with 2,2-bipyridyl, 1,10-phenanthroline,

Synthesis, chemistry and structures of complexes of the dioxovanadium(V) halides VO2F and VO2Cl.

Neither VO2F nor VO2Cl form isolable complexes with MeCN, thf or MeO(CH2)2OMe, and both are reduced by P-, As-, S- or Se-donor ligands.

A crystallographic and DFT study on a NHC complex of niobium oxide trifluoride

Abstract The complex [NbOF3(Ipr)]2, 1, was afforded in crystalline form by reaction of NbF5 with the bulky NHC ligand 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene (IPr) in toluene by slow contact

Discrete GeF5- Anion Structurally Characterized with a Readily Synthesized Imidazolium Based Naked Fluoride Reagent.

It is demonstrated that the role of bulky cation is not solely due to steric hindering but also due to electrostatic effects, which are important in the design of such uncommon species.

Equilibration between a Phosphine−Cobalt Complex and an Analogous Complex Containing an N-Heterocyclic Carbene: The Thermodynamics of a Phosphine−Carbene Exchange Reaction

The reaction of CpCo(PPh3)Me2 with the N-heterocyclic carbene 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene (IPr) does not result in complete substitution of the PPh3, as expected, but rather in

Coordination Compounds of Niobium(IV) Oxide Dihalides Including the Synthesis and the Crystallographic Characterization of NHC Complexes.

Compounds 3 and 4, whose molecular structures have been ascertained by X-ray diffraction, represent very rare examples of crystallographically characterized niobium-NHC systems.

Back-Donation in High-Valent d0 Metal Complexes: Does It Exist? The Case of NbV.

It is demonstrated that the metal center is really capable of back-donation to the carbene ligand by a charge flux that involves the chloride in the trans position and, directly, the metal.

Cationic tungsten-oxo-alkylidene-N-heterocyclic carbene complexes: highly active olefin metathesis catalysts.

These first neutral and cationic W-oxo-alkylidene-N-heterocyclic carbene (NHC) catalysts are reported, allowing for turnover numbers up to 10,000 in various olefin metathesis reactions including alkenes bearing nitrile, sec-amine, and thioether groups.
