All-inorganic 1D chain-based architecture of a novel dimanganese-substituted Keggin polyoxotungstate


Car, P-E; Spingler, B; Weyeneth, S; Patscheider, J; Patzke, Greta R (2013). All-inorganic 1D chain-based architecture of a novel dimanganese-substituted Keggin polyoxotungstate. Polyhedron, 52:151-158.

Abstract

A new dimanganese Keggin-type polyoxotungstate K6[Mn2SiW10O37(OH)(H2O)]·11H2O (1) with 1D chains was obtained from a one-pot solution approach. The title compound was characterized with a wide range of analytical techniques including single crystal X-ray diffraction as well as various spectroscopic techniques, and its magnetic behavior was investigated. The novel dimanganese-substituted Keggin ion of (1) is constructed from a divacant {SiW10O37} subunit incorporating MnII and MnIII ions. The emerging building blocks self-organize into new 1D chain-like POM architectures via Mn–O–W bridges that are rarely observed among this compound class. Water oxidation performance and long-term structural stability of (1) were investigated.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
