In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Syntheses and structural characterization of three new coordination polymers of [Ag(PPIA)·H2O]n, [Cu(PPIA)2·2H2O]n and [Zn(PPIA)2(H2O)2]n; PPIA = 3-pyridinepropionic acid, published in 2006-11-03, which mentions a compound: 3724-19-4, mainly applied to silver pyridinepropionic acid coordination polymer preparation structure; copper pyridinepropionic acid coordination polymer preparation structure; zinc pyridinepropionic acid coordination polymer preparation structure; crystal structure transition metal pyridinepropionic acid coordination polymer, Recommanded Product: 3-Pyridinepropionic acid.
The syntheses and crystal structures of three new coordination polymers [Ag(PPIA)·H2O]n (PPIA = 3-pyridinepropionic acid) (1), [Cu(PPIA)2·2H2O]n (2), and [Zn(PPIA)2(H2O)2]n (3), are reported. The reactions of 3-pyridinepropionic acid with AgNO3, Cu(NO3)2·6H2O and Zn(NO3)2·6H2O in MeOH afforded complexes 1-3, resp. Single-crystal x-ray crystallog. structure determinations show that complexes 1, 2 and 3 crystallize in the space groups P1̅ , Pbca and P21/n, resp. The Ag(I) centers in 1 adopt a slightly distorted T-shaped geometry, while the Cu(II) centers in 2 exhibit a distorted square planer coordination geometry and the Zn(II) centers in 3 adopt a distorted octahedral coordination geometry. The metal centers in 1-3 coordinate to both the pyridyl and carboxylate groups to form 1-dimensional polymeric chains and two-dimensional framework structures, resp. The 1-dimensional chain complex of 1 or the two-dimensional frameworks of 2 and 3 are also linked to form three-dimensional networks through H bonds.
This literature about this compound(3724-19-4)Recommanded Product: 3-Pyridinepropionic acidhas given us a lot of inspiration, and I hope that the research on this compound(3-Pyridinepropionic acid) can be further advanced. Maybe we can get more compounds in a similar way.
