“Transition Metal-containing Heteropolyngstates”
Najla Atiyeh 1301, Beirut campus
The Department of Natural Sciences and part of the Research Seminar and Journal Club Series are organizing a seminar titled: "Transition Metal-containing Heteropolyngstates."
The Seminar will be conducted by Dr. Bassem Bassil from Jacobs university, School of Engineering and Sciences, Bremen, Germany.
All are welcome to attend.
Abstract
Lacunary (lacuna = void) heteropolytungstates are known to act as inorganic multidentate ligands which can coordinate to eletrophilic centers (especially transition metals) through oxygen atom donors at the lacunary sites.The combination of transition metals with lacunary
heteropolytungstates is part of the TMSP (Transition Metal-Substituted Polyoxometalates) subclass, which has attracted increasing interest due to the properties of these compounds in magnetism, catalysis and electrochemistry.Interaction of the dilacunary decatungstate precursors [XW10O36]8- (X = Si, Ge) with different transition metals has led to a series of novel molecular assemblies with variable structural architecture and properties.Interaction of the trilacunary nonatungstate precursors [XW9O34]n-(X = Ge, Si n = 10, X = P n = 9) respectively with Ce3+, Mn2+ and Co2+ resulted in molecular, high-nuclearity compounds.
