Silver co-ordination compounds with aliphatic nitriles containing amino nitrogen as H bond donor or additional metal binding site: formation of a ring, a chain, a polymeric sheet and a 3D polymeric channeled structure was written by Erxleben, Andrea. And the article was included in CrystEngComm in 2002.HPLC of Formula: 7528-78-1 This article mentions the following:
Three coordination polymers and a discrete 20-membered macrometallacycle were prepared by crystallization of Ag salts with the conformationally flexible, polyfunctional ligands N-(2-cyanoethyl)glycine (ceg), 3,3-iminodipropionitrile (idpn) and tris(2-cyanoethyl)amine (tca). Single-crystal x-ray analyses of [Ag2(tca)2](ClO4)2 (1), [Ag(idpn)]ClO4 (2), [Ag(ceg)]CF3SO3 (3) and [Ag(ceg)]ClO4·0.5H2O (4) revealed a bimetallic macrocycle (1), a 2-dimensional sheet structure with 4.82 topol. (2), a 3-dimensional network structure with rhomboid channels (3) and a 1-dimensional chain structure (4). The rhomboid channels in 3 are generated by 36-membered macrometallacyclic subunits consisting of four Ag atoms and four ceg ligands with ceg binding through the carboxylate group and the nitrile N. The amino N of ceg is protonated and serves as a H bond donor for the triflate anions that are incorporated into the macrocycles, thus stabilizing the channeled structure. In the experiment, the researchers used many compounds, for example, 3,3′,3”-Nitrilotripropanenitrile (cas: 7528-78-1HPLC of Formula: 7528-78-1).
3,3′,3”-Nitrilotripropanenitrile (cas: 7528-78-1) belongs to nitriles. Nitrile function is a very important functional group because it can be manipulated to other functional groups such as carboxylic acid by hydrolysis or amine by reduction, respectively. In addition, Nitriles can react with alkynes, which leads to an increase in carbon chain length (carbocyanation).HPLC of Formula: 7528-78-1
