Complexes of copper(I) and silver(I) perchlorates with substituted 2-cyanopyridines was written by El-Sayed, Laila;Ragsdale, Ronald O.. And the article was included in Journal of Inorganic and Nuclear Chemistry in 1968.Reference of 1620-76-4 This article mentions the following:
ML2ClO4 [M = Cu, Ag; L = 4-methyl-2-cyanopyridine, 6-methyl-2-cyanopyridine, 4-nitro-2-cyanopyridine (I), 4-chloro-2-cyanopyridine (II)] were prepared by treating MClO4 with a 10-fold excess of L in CH2Cl2. AgLClO4 (L = I and II) were prepared in C6H6 by using a 1:1 mole ratio of metal ion to base. The IR spectra of the complexes indicate that the coordination of the pyridine occurs via the long pair of electrons on the nitrile N. In the experiment, the researchers used many compounds, for example, 4-Methylpicolinonitrile (cas: 1620-76-4Reference of 1620-76-4).
4-Methylpicolinonitrile (cas: 1620-76-4) belongs to pyridine derivatives. Pyridine is diamagnetic and has a diamagnetic susceptibility of â?8.7 à 10â? cm3·molâ?.The molecular electric dipole moment is 2.2 debyes. The standard enthalpy of formation is 100.2 kJ·molâ? in the liquid phase and 140.4 kJ·molâ? in the gas phase. Reduced pyridines, namely tetrahydropyridines, dihydropyridines and piperidines, are found in numerous natural and synthetic compounds. The synthesis and reactivity of these compounds have often been driven by the fact many of these compounds have interesting and unique pharmacological properties. Reference of 1620-76-4
