Application of 64479-78-3On November 1, 2018 ,《Synthesis and characterization of one, two and three-dimensional Cu(I) polymers supported by bipyridylamide ligands》 appeared in Polyhedron. The author of the article were Mugenzi, Clement; Powell, Douglas R.; Gerasimchuk, Nikolay N.; Yang, Lei. The article conveys some information:
Reaction of bipyridylamide ligands N-(3-pyridyl)nicotinamide (3-pna), N-(4-pyridyl)nicotinamide (4-pna) and N-(4-pyridyl)isonicotinamide (4-pina) with Cu(I) salts afforded four coordination polymers. The prepared complexes are [Cu(3-pna)2]SbF6 (1), [Cu(4-pna)2]SbF6 (2), [Cu(4-pina)(CH3CN)2]SbF6 (3), {[Cu2(4-pna)4](SbF6)2(H2O)}n (4), and [Cu(4-bpe)2](SbF6) (5). X-ray crystallog. anal. showed one-, two- and three-dimensional networks. The correlation between the pyridyl nitrogen donor disposition and dimensionality of the structures is discussed. Reflectance UV-visible and fluorescence spectroscopic methods were used to characterize the MLCT features of these complexes. Thermal stability of the coordination polymers under nitrogen was also studied. The experimental part of the paper was very detailed, including the reaction process of N-(Pyridin-4-yl)isonicotinamide(cas: 64479-78-3Application of 64479-78-3)
N-(Pyridin-4-yl)isonicotinamide(cas: 64479-78-3) belongs to amides. Because of the greater electronegativity of oxygen, the carbonyl (C=O) is a stronger dipole than the N–C dipole. The presence of a C=O dipole and, to a lesser extent a N–C dipole, allows amides to act as H-bond acceptors.“,” In primary and secondary amides, the presence of N–H dipoles allows amides to function as H-bond donors as well.
