Ligand-based reduction of CO(2) to CO mediated by an anionic niobium nitride complex.
The terminal nitride anion complex [Na][N[triple bond]Nb(N[(t)Bu]Ar)(3)] ([Na][1], Ar = 3,5-Me(2)C(6)H(3)) reacts quantitatively with CO(2) to give the carbamate complex [Na][O(2)CN[triple bond]Nb(N[(t)Bu]Ar)(3)] ([Na][O(2)C-1]). The structure of [Na][O(2)C-1] as the bis-12-crown-4 solvate, as determined by X-ray crystallography, displays a unique N-bound carbamate ligand without any metal-oxyg...
متن کاملElectrocatalytic reduction of CO2 to CO by polypyridyl ruthenium complexes.
Electrocatalytic reduction of CO(2) by [Ru(tpy)(bpy)(solvent)](2+) (tpy = 2,2':6',2''-terpyridine, bpy = 2,2'-bipyridine) and its structural analogs is initiated by sequential 1e(-) reductions at the tpy and bpy ligands followed by rate limiting CO(2) addition to give a metallocarboxylate intermediate. It undergoes further reduction and loss of CO.
متن کاملSynthesis and Characterization of a Niobium Nitride Precursor and Niobium Nitride Powder
Anodic dissolution of Nb foil in an electrolyte solution containing liquid NH3 and NH4Br produces an insoluble precursor that can be calcined to yield phase-pure NbN. Infrared spectroscopy is consistent with a precursor having the general formula NbXn(NH2)5-npNH3. By changing the calcination conditions, the phase of the resulting NbN powder can be varied. For example, calcining in pure Ar yield...
متن کاملMechanistic studies of CO2 reduction to methanol mediated by an N-heterocyclic germylene hydride.
The labile germylene hydride L(Cy)GeH is capable of activating CO2 affording the corresponding formate L(Cy)GeOCH([double bond, length as m-dash]O) (2) (L(Cy) = cyclo-C6H8-1-NAr-2-C(Ph)NAr, Ar = 2,6-iPr2C6H3). Compound and the previously reported LGeOCH([double bond, length as m-dash]O) (L = CH(MeC[double bond, length as m-dash]NAr)2, Ar = 2,6-iPr2C6H3) (2) could be further converted to methano...
متن کاملReduction of CO2 by Pyridine Monoimine Molybdenum Carbonyl Complexes: Cooperative Metal-Ligand Binding of CO2.
[((Ar) PMI)Mo(CO)4 ] complexes (PMI=pyridine monoimine; Ar=Ph, 2,6-di-iso-propylphenyl) were synthesized and their electrochemical properties were probed with cyclic voltammetry and infrared spectroelectrochemistry (IR-SEC). The complexes undergo a reduction at more positive potentials than the related [(bipyridine)Mo(CO)4 ] complex, which is ligand based according to IR-SEC and DFT data. To pr...
