Designing magnesium-selective ligands using coordination chemistry principles

چکیده
Progress in the selective binding and detection of magnesium ions has been slower than other biologically important divalent metal like calcium zinc. The most widely used ligands for Mg2+ are by no means optimal, as they not it. Nevertheless, is a major cation all cells, with physiologically critical functions. There need improved sensors Mg2+. In this review, we consider how an appreciation fundamental coordination chemistry principles may inform development new A number representative examples differing denticity discussed context. Low-denticity such ?-keto acids offer best selectivities, but speciation issue polydentate pyrophosphate complete sphere. High-denticity based on aminocarboxylates APTRA typically highest stability constants, bind Ca2+ Zn2+ more strongly We highlight recent featuring related aminophosphinates, where longer bonds smaller bite angles favour selectivity towards Macrocyclic receptors explicitly.

Coordination Chemistry in magnesium battery electrolytes: how ligands affect their performance
Magnesium battery is potentially a safe, cost-effective, and high energy density technology for large scale energy storage. However, the development of magnesium battery has been hindered by the limited performance and the lack of fundamental understandings of electrolytes. Here, we present a study in understanding coordination chemistry of Mg(BH₄)₂ in ethereal solvents. The O donor denticity, ...
متن کاملOuter-sphere coordination chemistry: amido-ammonium ligands as highly selective tetrachloridozinc(II)ate extractants.
Eight new amido functionalized reagents, L(1)-L(8), have been synthesized containing the sequence of atoms R(2)N-CH(2)-NR'-CO-R″, which upon protonation forms a six-membered chelate with a hydrogen bond between the tertiary ammonium N-H(+) group and the amido oxygen atom. The monocationic ligands, LH(+), extract tetrachloridometal(II)ates from acidic solutions containing high concentrations of ...

Liquid-assisted grinding allows the rapid, waste-free and one-pot synthesis of a variety of magnesium drug derivatives directly from the excipient MgO; such reactivity is relevant for the behaviour of ibuprofen formulations involving MgO and can be used for oxide-based mechanosynthesis of metal-organic salts, discrete complexes and carboxylate clusters involving magnesium and pharmaceutically a...
متن کاملVIII-B Coordination Chemistry of Sterically Hindered Ligands and Multidentate Ligands, and Activation of Small Molecules
Thiolate complexes continue to attract considerable attention due to their unique chemical properties and structural diversity. Since thiolate groups meet the electronic and steric requirements necessary to stabilize a wide variety of metal complexes, they have been used as auxiliary ligands. On the other hand, thiolate complexes are known to undergo chemistry at the sulfur center, including ox...
