Structural consequences of fluoride incorporation into oxovanadium-xylyldiphosphonates with charge compensating copper(II)-imine components

Hydrothermal synthesis, structure, heterogeneous catalytic activity and photoluminescent properties of a novel homoleptic Sm(III)-organic framework

“…The hydrothermal method provides an efficient technique for synthesizing MOFs. Factors such as variations in temperature, pH, reactant stoichiometry, the presence or absence of organic cations, and even the fill volume have been shown to influence the product outcome [9,10]. One potential application of transition metal pyridinecarboxylate complexes is the oxidation of organic substrates.…”

Assembly of a Hexameric Cluster of Polyoxomolybdotriphosphonate Builts from [Zn(H2O){TeMo6O21}{N(CH2PO3)3}]6– Subunits and Its Optical and Catalytic Properties

“…Polyoxometalates (POMs), as anionic transition-metal (e.g., Mo, W, V, Nb, Ta) oxygen-rich clusters, have been investigated not only because of their captivating structural and compositional diversity but also because of their potential applications in spectroscopy, biomedicine, magnetism, materials science, and nanotechnology. − In the last few decades, we have seen the tremendous development of POMs. − It is worth mentioning that organic–inorganic POMs, as a branch of POMs, have attracted much attention because they possess distinct structural characteristics and new properties: for example, as sorbents, ion exchangers, ionic conductors, nonlinear optical materials, sensors, catalysts, and so on. − The organic or organometallic ligands inserted into POM building blocks (such as organotin, carboxylic acid, alkoxy, organosilicon, and organophosphonate) have achieved a dominant position. − Within this field, great effort has been made and considerable attention has been given to organophosphonate-based POM derivatives, which have been developed largely by Zubieta, , Dolbecq, , Kortz, , and Mialane …”

“…18−23 The organic or organometallic ligands inserted into POM building blocks (such as organotin, carboxylic acid, alkoxy, organosilicon, and organophosphonate) have achieved a dominant position. 24−28 Within this field, great effort has been made and considerable attention has been given to organophosphonate-based POM derivatives, which have been developed largely by Zubieta, 29,30 Dolbecq,31,32 Kortz, 33,34 and Mialane. 35 To date, organophosphonate-functionalized POMs, including organophosphonate-modified polyoxotungstates (W/O/ RPO 3 2− ), organophosphonate-modified polyoxovanadates (V/ O/RPO 3 2− ), and organophosphonate-modified polyoxomolybdates (Mo/O/RPO 3 2− ), have been reported (R = CH 2 , CH 3 CH 2 , CH 2 C 6 H 4 NH 3 , HOOCC 6 H 4 , HOOCCH 2 , CH 2 CH 2 NH 3 , etc.).…”

Orientational disorder and phase transitions in ammonium oxofluorovanadates, (NH4)3VOF5 and (NH4)3VO2F4

“…Vanadium oxide fluorides (VOFs) exhibit rich and extensive structural chemistry owing to the ability of vanadium to adopt different oxidation states and coordination environments, forming various basic building units (BBUs) that can be examined in varied systems (Adil et al, 2010;Aidoudi et al, 2011Aidoudi et al, , 2014Aldous & Lightfoot, 2009;Aldous et al, 2007a,b;Chang et al, 2016;DeBurgomaster et al, 2010;Donakowski et al, 2014;Gautier et al, 2012Gautier et al, , 2015Senchyk et al, 2012;Smith et al, 2014;Yeon et al, 2015). The formation of diverse VOFs with new BBUs can be expected to create unprecedented crystal structures giving rise to interesting physical properties.…”
