The synthesis and molecular structure of a monomeric diplatinum(II) complex composed of mono-lacunary α-Keggin polyoxometalate is described. The polyoxometalate, Cs(3)[α-PW(11)O(39){cis-Pt(NH(3))(2)}(2)]·8H(2)O (Cs-1), afforded by a stoichiometric reaction of mono-lacunary Keggin polyoxotungstate with cis-diamminedichloroplatinum(ii) in water, followed by crystallization from water, was obtaine...
Understanding the structural and electronic mechanisms by which catalysts activate and deactivate during use is crucial to the intelligent design of more efficient chemical syntheses. Atomic resolution electron microscopy is used in conjunction with bulk characterization tools including as X-ray Diffraction (XRD), Ultraviolet–visible Diffuse Reflectance Spectroscopy (UV–vis DRS) and X-ray Absor...
Polyoxometalates are non-nucleoside analogs that have been proven to exhibit broad-spectrum antiviral activity. In particular, Cs2K4Na[SiW9Nb3O40].H2O 1 shows low toxicity and high activity against HBV. The preclinical pharmacokinetics of Compound 1 in rats were characterized by establishing and applying inductively coupled plasma-mass spectrometry method to determine the concentration of W in ...
A mixed-addenda W/Mo hybrid polyoxometalate cluster - K 6 [P 2 W 15 Mo O 61 (POC H 5 ) ] ( 1 was synthesized from the condensation of 10 and phenylphosphonic acid under acidic conditions. Single-crystal X-ray diffraction confirmed structure presence two centers in cap lacunary cluster. The electronic effects metal substitution were studied by cyclic voltammetry, spectroelectrochemistry electron...
The use of electrochemistry in organic synthesis (sometimes termed electro-organic synthesis, or just “electrosynthesis”) is a field that attracting ever-increasing attention on account its ability to deliver reaction outcomes cannot be achieved any other way and potential replace toxic and/or sacrificial reagents with cleanly-generated electricity. In the simplest incarnation an substrate unde...
A new polyoxovanadate [Zn2(dien)3][[Zn(dien)]2As4V16O42(H2O)] x 3H2O (1, dien = diethylenetriamine) has been hydrothermally synthesized and structurally characterized by EA, IR, TGA, magnetic measurement and single crystal X-ray diffraction. X-Ray diffraction analyses reveal that 1 exhibits the first [As4V16O42(H2O)]-containing polyoxometalate. In 1, the adjacent [As4V16O42(H2O)] clusters are l...
