A bis-pyrazolate Pincer on Reduced Cr Deoxygenates CO2: Selective Capture of the Derived Oxide by Cr(II).

Summary of "A bis-pyrazolate Pincer on Reduced Cr Deoxygenates CO2: Selective Capture of the Derived Oxide by Cr(II)."

Reduction of the bis-(pyrazolyl)pyridine complex [LCr]2 with stoichiometric KC8 in THF produces a species that is reactive with CO2 to produce an aggregate composed of paramagnetic K2L2Cr2(CO3) linked by KCl into a product of formula [K2L2Cr2(CO3)]4∙2KCl. X-ray diffraction reveals a pincer hydrocarbon exterior and an inorganic interior composed of K+, Cl- and carbonate oxygens. Every Cr is five coordinate and square pyramidal, with the axial N donor weakly bonded to Cr due to the Jahn-Teller effect of a high spin d4 configuration. Reaction with 13CO2 confirms that carbonate here is derived from CO2, that oxide is derived from CO2, and that CO is indeed released, since it is not a competent ligand to Cr(II). Guiding principles for selectivity in CO2 reduction are deduced from the diverse successful molecular constructs to date.

Medical and Biotech [MESH] Definitions

A non-selective inhibitor of nitric oxide synthase. It has been used experimentally to induce hypertension.

A free radical gas produced endogenously by a variety of mammalian cells, synthesized from ARGININE by NITRIC OXIDE SYNTHASE. Nitric oxide is one of the ENDOTHELIUM-DEPENDENT RELAXING FACTORS released by the vascular endothelium and mediates VASODILATION. It also inhibits platelet aggregation, induces disaggregation of aggregated platelets, and inhibits platelet adhesion to the vascular endothelium. Nitric oxide activates cytosolic GUANYLATE CYCLASE and thus elevates intracellular levels of CYCLIC GMP.

A potent mutagen and carcinogen. This compound and its metabolite 4-HYDROXYAMINOQUINOLINE-1-OXIDE bind to nucleic acids. It inactivates bacteria but not bacteriophage.

A potent mutagen and carcinogen. It is a reduction product of 4-NITROQUINOLINE-1-OXIDE. It binds with nucleic acids and inactivates both bacteria and bacteriophage.

A group of FLAVONOLS based on kaempferol. They are derived from naringenin and can be hydroxylated to QUERCETIN or reduced to leucopelargonidin.
