Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. In an article, author is Moghzi, Faezeh, once mentioned the application of 14508-49-7, Name is 2-Chloropyrazine, molecular formula is C4H3ClN2, molecular weight is 114.53, MDL number is MFCD00006124, category is pyrazines. Now introduce a scientific discovery about this category, COA of Formula: C4H3ClN2.
Four new praseodymium(III) metal-organic compounds varying in dimensionality from 0D to 3D have been designed and synthesized based on N-heterocyclic polycarboxylic acids, including pyridine-2,6-dicarboxylic acid (H(2)pydc) and pyrazine-2,3-dicarboxylic acid (H(2)pzdc). Altering the concentration of piperazine (pip, ancillary ligand) enables control over the dimensionality of the compound by switching between the 0D [H(2)pip][Hpip][Pr(pydc)(3)]center dot 4H(2)O (I) and the 1D {[Pr(pydc)( Hpydc)(H2O)(2)]center dot 4H(2)O}(n) (II) coordination polymer (CP). Upon replacing H(2)pydc with H2pzdc, CP II is converted to the 2D CP [Pr(pzdc)(Hpzdc)(H2O)(3)](n) (III) and using the metalloligand [Zn(Hpzdc)(2)(H2O)(2)](2-) the 3D heterometallic CP {[Pr2Zn(pzdc)(4)(H2O)(6)]center dot 2H(2)O}(n) (IV) is formed. Compound IV shows high stability in the absence of uncoordinated solvent molecules and is stable up to 400 degrees C, even in the presence of humidity. Therefore, IV was utilized for iodine adsorption in the vapour phase and in the presence of humidity. The results confirm the remarkable potential of IV for reversible adsorption of iodine vapour.
