A one-dimensional chain of manganese(ii) bridged peroxomolybdate isolated from an aqueous Mn–polymolybdate–H₂O₂ system

Abstract

A new manganese(II)-peroxomolybdate complex, Cs4[Mn(OH2)2(Mo7O22(O2)2)]·4.25H2O (Cs-1), was isolated from the aqueous solution containing manganses(II) sulfate, sodium heptamolybdate and hydrogen peroxide by the addition of Cs+ salt. Cs-1 was characterized by...

Four Chromic Compounds Constructed from Keggin Polyoxometalates and Viologens with Applications in Ultraviolet, Metal Ion Detection, and Ink-Free Printing

“…Polyoxometalate (POM) is an important branch of the inorganic field, which is a kind of metal oxygen clusters formed by oxygen connection of pretransition metal ions. − Until now, POM has been widely studied as a functional component and applied in many fields such as light, electricity, and magnetism. − Moreover, the surface of POMs is rich in electrons, which can provide electrons easily. Thus, POMs own excellent redox properties, inducing the applications in electrochemistry and catalysis. − Furthermore, the characteristics of rich electrons of POMs can conduce electron transition, which makes POMs act as precursors of chromic materials .…”
