Zinc and Cadmium Complexes of Pyridinemethanol Carboxylates: Metal Carboxylate Zwitterions and Metal–Organic Frameworks

ChemPlusChem, 2020
AbstractThe heterofunctional lactone furo[3,4‐b]pyridin‐5(7H)‐one (L1) undergoes a coordination‐induced ring‐opening reaction with Zn(NO3)2 ⋅ 6H2O to yield the zwitterionic [Zn(L1′)2(H2O)2] (1, L1′=2‐(hydroxymethyl)nicotinate) with an uncoordinated carboxylate.

Metal–Organic Frameworks via Emissive Metal‐Carboxylate Zwitterion Intermediates

ChemPlusChem, 2015
AbstractPyridinemethanol‐carboxylate esters form octahedral complexes with Zn(NO3)2 in aqueous DMF that subsequently undergo hydrolysis at elevated temperatures to form metal‐carboxylate zwitterions. In situ deprotonation of the hydroxy group leads to thermally robust, neutral MOFs.

Effect of benzoic acid substituents and additional functional groups of ancillary ligands in modulating the nuclearity and aggregation behavior of transition metal carboxylates

Inorganica Chimica Acta, 2019
Structural modulation of transition metal carboxylates has been studied by employing different auxiliary ligands in the reactions of metal acetates with substituted benzoic acids.

Synthesis of Alkali Metal Carboxylates and Carboxylic Acids Using “Wet” and “Anhydrous” Alkali Metal Hydroxides

Chemical Reviews, 2010
Alkali metal carboxylates and carboxylic acids were synthesized using wet and anhydrous alkali metal hydroxides. Lithium, sodium, potassium, and cesium hydroxides, in hydroxylic solvents, have been used indistinctively to perform various reactions. An aqueous solution of tetrabutylammonium hydroxide (TBAH) in methanol, t-butanol, and THF allows the ...

Carboxylic acids as metal extractants

Talanta, 1974
One of the problems in the extraction of trace elements is that matrix elements must usually be masked, involving the addition of large amounts of extra reagent and thus increasing the risk of contamination. If the maxtrix element is to be removed, an extraction system of high capacity is needed to avoid dilution effects. In this respect, long-chain or

Microporous Materials of Metal Carboxylates

Journal of Solid State Chemistry, 2000
Copper(II) terephthalate absorbs a large amount of gases such as N2, Ar, O2, and Xe. The maximum amounts of absorption of gases were 1.8, 1.9, 2.2, and 0.9 mole per mole of the copper(II) salt for N2, Ar, O2, and Xe, respectively, indicating that the gases were not adsorbed on the surface but occluded within the solid.

Discovery and development of microporous metal carboxylates

The Chemical Record, 2005
AbstractWe have found a form of copper(II) terephthalate that occluded an enormous amount of gases such as N2, Ar, O2, and Xe. Copper(II) terephthalate is the first metal complex found capable of adsorbing gases. This complex has opened a new field of adsorbent chemistry and is recognized as a leader in the construction of microporous metal complexes ...
