Qin, Zengquan; Jennings, Michael C.; Puddephatt, Richard J. published their research in Chemical Communications (Cambridge, United Kingdom) on December 21 ,2001. The article was titled 《Stacked molecular triangles: self-assembly using coordination chemistry and hydrogen bonding》.HPLC of Formula: 64479-78-3 The article contains the following contents:
The combination of the cis-blocked platinum(II) unit (bu2bipy)Pt2+ with the unsym. bis(pyridine) ligand 4-NC5H4C(:O)NH-4-C5H4N (L) gives the mol. triangle complex [{Pt(bu2bipy)(μ-L)}3]6+, which forms stacked pairs in the solid state through intertriangle NH···OC hydrogen bonds and Pt···OC secondary bonds. The crystal structure of [{(bu2bipy)Pt(μ-L)}3](CF3SO3)6·Me2CO·3H2O was determined The analogous palladium(II) complex was prepared as the BF4- salt.N-(Pyridin-4-yl)isonicotinamide(cas: 64479-78-3HPLC of Formula: 64479-78-3) was used in this study.
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.
