Pyridinesilver Tetraoxometallate Complexes: Overview of the Synthesis, Structure, and Properties of Pyridine Complexed AgXO₄ (X = Cl, Mn, Re) Compounds

Abstract

We reviewed the synthesis, structure, and properties of pyridine complexes of AgXO4 (X = Cl, Mn, and Re) compounds with various compositions ([AgPy2] XO4, [AgPy2XO4]·0.5Py, [AgPy4] XO4, and 4 [AgPy2XO4] [AgPy4] XO4). We also clarified the controversial information about the existence and composition of pyridine complexes of silver permanganate, used widely as mild and selective oxidants in organic chemistry. We discussed in detail the available structural and spectroscopic (IR, Raman, and UV) data and thermal behavior, including the existence and consequence of quasi-intramolecular reactions between the reducing ligand and anions containing oxygen.
