In 2019,Australian Journal of Chemistry included an article by Wegeberg, Christina; Nielsen, David; Mossin, Susanne; Abrahams, Brendan F.; McKee, Vickie; McKenzie, Christine J.. SDS of cas: 100-48-1. The article was titled 《Reversible and Vapochromic Chemisorption of Ammonia by a Copper(II) Coordination Polymer》. The information in the text is summarized as follows:
The single crystal x-ray structure determination of {[Cu(tpt)(o-phthalate)]·3 1/3(C2H2Cl4)}n (tpt = 2,4,6-tri-4-pyridyl-1,3,5-triazine, C2H2Cl4 = 1,1,2,2-tetrachloroethane = TCE) shows a 3-dimensional network in which Cu centers are linked by 3-connecting tpt ligands with the topol. of a 12,3 net. Cu centers are further linked by o-phthalate dianions. The copper coordination geometry is square pyramidal, with o-phthalate oxygen donors trans to each other in the basal plane and the remaining positions taken by the pyridines of three linking tpt units. The solvent accessible void space is ∼65%. The pale blue-green crystalline desolvate, obtained by heating to 200° or washing the TCE solvate with acetone is [Cu(tpt)(o-phthalate)]n. Powder x-ray diffraction and ESR spectroscopy show that the crystal structure and the Cu geometry changes upon desolvation. The crystalline desolvated phase sorbs two equivalent of ammonia per copper ion. The adduct, mauve [Cu(tpt)(o-phthalate)(NH3)2]n, shows reasonable crystallinity and is stable up to ∼150° under ambient conditions before the reversible desorption (min. 10 cycles) of the guest ammonia. The color change and high desorption temperature, along with changes in g values, is suggestive of chemisorption in two steps with Cu-ammine bonding in the loaded phase. In the experimental materials used by the author, we found 4-Cyanopyridine(cas: 100-48-1SDS of cas: 100-48-1)
4-Cyanopyridine(cas: 100-48-1) belongs to pyridine. Pyridines are often used as catalysts or reagents; particular notice has been paid recently to how pyridine coordinates to metal centers enabling a wide range of valuable reactions. SDS of cas: 100-48-1
