Gaskin, Gabrielle J.; LaDuca, Robert L. published an article in IUCrData. The title of the article was 《Poly[diaqua[μ4-2-(carboxylatomethoxy)benzoato][μ2-2-(carboxylatomethoxy)benzoato]dicadmium(II)]》.Electric Literature of C11H9N3O The author mentioned the following in the article:
In the title compound, [Cd2(C9H6O5)2(H2O)2]n, the crystallog. distinct CdII cations are coordinated in pentagonal-bipyramidal and octahedral fashions. The 2-(carboxymethoxy)benzoate (cmb) ligands connect the Cd atoms into [Cd2(cmb)2(H2O)2)]n coordination polymer ribbons that are oriented along the a-axis direction. Supramol. layers are formed parallel to (01 [inline formula omitted] ) by O-H···O hydrogen bonding between the ribbons. The supramol. three-dimensional crystal structure of the title compound is then constructed by π-π stacking interactions with a centroid-centroid distance of 3.622 (2) Å between cmb ligands in adjacent layer motifs. The experimental process involved the reaction of N-(Pyridin-4-yl)isonicotinamide(cas: 64479-78-3Electric Literature of C11H9N3O)
N-(Pyridin-4-yl)isonicotinamide(cas: 64479-78-3) belongs to amides.Electric Literature of C11H9N3OAmides 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.
