《Donor disposition and aliphatic conformation effects on structure in luminescent zinc dicarboxylate coordination polymers with isomeric dipyridylamide coligands》 was published in CrystEngComm in 2013. These research results belong to Uebler, Jacob W.; Wilson, Julie A.; LaDuca, Robert L.. Recommanded Product: N-(Pyridin-4-yl)isonicotinamide The article mentions the following:
Hydrothermal reaction of zinc nitrate, a four-carbon chain dicarboxylic acid, and one of three isomeric dipyridylamide coligands has afforded a family of six new coordination polymers, which were structurally characterized by single-crystal x-ray diffraction. The binding modes and conformations of the dicarboxylate ligands and the nitrogen donor disposition within the dipyridylamide coligands provide crucial structure-directing roles in this system. {[Zn(fum)(3-pina)]·1.5H2O}n (1, fum = fumarate, 3-pina = 3-pyridylisonicotinamide) has a 4-fold interpenetrated 43628 sra topol. [Zn(fum)(4-pna)]n (2, 4-pna = 4-pyridylnicotinamide) possesses a 4-fold interpenetrated 66dia topol., while [Zn(fum)(4-pina)]n (3, 4-pina = 4-pyridylisonicotinamide) has a 2-fold interpenetrated 41263pcu topol. with dimeric cluster nodes. [Zn3(mal)2(OH)2(4-pina)2]n (4, mal = maleate) has neutral [Zn3(mal)2(OH)2]n ribbons linked into a (3,6) triangular layer. [Zn(suc)(4-pina)]n (5, suc = succinate) displays an uncommon 6-connected self-penetrated 446108 mab topol., while instead [Zn(suc)(4-pna)]n (6) has a simple corrugated (4,4) grid structure. Thermal and luminescent properties of these new materials also were studied. The experimental process involved the reaction of N-(Pyridin-4-yl)isonicotinamide(cas: 64479-78-3Recommanded Product: N-(Pyridin-4-yl)isonicotinamide)
N-(Pyridin-4-yl)isonicotinamide(cas: 64479-78-3) belongs to amides.Recommanded Product: N-(Pyridin-4-yl)isonicotinamideAmides are pervasive in nature and technology. Proteins and important plastics like Nylons, Aramid, Twaron, and Kevlar are polymers whose units are connected by amide groups (polyamides); these linkages are easily formed, confer structural rigidity, and resist hydrolysis.
