Garcia-Romero, Alvaro; Martin-Alvarez, Jose M.; Miguel, Daniel; Wright, Dominic S.; Alvarez, Celedonio M.; Garcia-Rodriguez, Raul published the article 《Cation- and Anion-Mediated Supramolecular Assembly of Bismuth and Antimony Tris(3-pyridyl) Complexes》. Keywords: pyridyl bismuth antimony ligand preparation crystal mol structure complexation; copper silver complexation supramol bismuth antimony pyridyl.They researched the compound: Silver(I) trifluoromethanesulfonate( cas:2923-28-6 ).Quality Control of Silver(I) trifluoromethanesulfonate. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:2923-28-6) here.
The use of antimony and bismuth in supramol. chem. has been largely overlooked in comparison to the lighter elements of Group 15, and the coordination chem. of the tripodal ligands [Sb(3-py)3] and [Bi(3-py)3] (L) containing the heaviest p-block element bridgehead atoms has been unexplored. Authors show that these ligands form a common hybrid metal-organic framework (MOF) structure with Cu(I) and Ag(I) (M) salts of weakly coordinating anions (PF6-, SbF6-, and OTf-), composed of a cationic substructure of rhombic cage (M)4(L)4 units linked by Sb/Bi-M bonding. The greater Lewis acidity of Bi compared to Sb can, however, allows anion···Bi interactions to overcome Bi-metal bonding in the case of BF4-, leading to collapse of the MOF structure (which is also seen where harder metals like Li+ are employed). This study therefore provides insight into the way in which the electronic effects of the bridgehead atom in these ligand systems can impact their supramol. chem.
From this literature《Cation- and Anion-Mediated Supramolecular Assembly of Bismuth and Antimony Tris(3-pyridyl) Complexes》,we know some information about this compound(2923-28-6)Quality Control of Silver(I) trifluoromethanesulfonate, but this is not all information, there are many literatures related to this compound(2923-28-6).
