The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 5-Hydroxynicotinic acid(SMILESS: O=C(O)C1=CN=CC(O)=C1,cas:27828-71-3) is researched.Category: quinazoline. The article 《Poly[tetraaqua(5-hydroxypyridin-1-ium-3-carboxylato-κO3)tris(μ-oxalato-κ4O1,O2:O1′,O2′)dieuropium(III)]》 in relation to this compound, is published in Acta Crystallographica, Section E: Structure Reports Online. Let’s take a look at the latest research on this compound (cas:27828-71-3).
In the title compound, [Eu2(C6H5NO3)2(C2O4)3(H2O)4]n, the EuIII atom is bonded to one O atom from a monodentate 5-hydroxypyridin-1-ium-3-carboxylate ligand, six O atoms from three oxalate ligands and two water mols., exhibiting a highly distorted tricapped trigonal geometry. Three independent oxalate ligands, each lying on an inversion center, bridge the EuIII atoms, forming a brickwall-like layer parallel to (001), which is stabilized by intralayer O-H···O hydrogen bonds. The layers are further linked through interlayer O-H···O and N-H···O hydrogen bonds and π-π interactions between the pyridine rings [centroid-centroid distance = 3.5741(14) Å] into a three-dimensional supramol. network.
From this literature《Poly[tetraaqua(5-hydroxypyridin-1-ium-3-carboxylato-κO3)tris(μ-oxalato-κ4O1,O2:O1′,O2′)dieuropium(III)]》,we know some information about this compound(27828-71-3)Electric Literature of C6H5NO3, but this is not all information, there are many literatures related to this compound(27828-71-3).
