Design and Assembly of Covalently Functionalised Polyoxofluorovanadate Molecular Hybrids

“…The employed synthetic procedure for the preparation of this new family of mixed-valent {V 14 }c lusters involves the utilisation of the binuclear oxofluorovanadate species, [V IV 2 O 2 F 4 -(m-F) 2 (OH 2 ) 2 ] 2À .T hree divanadium(IV)c omplexes werep repared. Twow ere isolated as pyridinium (pyH + )a nd imidazolium (imH + )s alts that were precursors for the {V 14…”

“…Another noteworthy feature of oxofluorovanadates is their preference for slightly less electropositive metal centres, for example, V IV instead of V V , which is due to the high electronegativity of the fluoride ion. The consequence of the introduced characteristics gives rise to interesting physical properties such as magnetism, catalysis and nonlinear optical activity . An interesting observation of the vanadium fluoride and oxofluoride chemistry is the tendency for polymerisation, and formation of products which exhibit 2D and 3D structures constructed by oligomeric, chain and ladder shaped building blocks .…”

Hydrothermal synthesis and structure of a two-dimensional bimetallic copper–molybdophosphonate, [{Cu4(H2O)2(phenbisterpy)2(HO3P(CH2)4PO3H)}(Mo4FO12)2{O3P(CH2)4PO3}]·4H2O, constructed from {Mo4FO12}1− clusters and copper-ligand chains (phenbisterpy=1,4-bis(2,2′:6′,2′′-terpyridin-4′-yl)benzene)

“…It is noteworthy that under the hydrothermal conditions of synthesis, HF is commonly introduced as a solubilizing reagent. While the fluoride is intended to be a spectator ion, incorporation to provide metal oxyfluoride species has been observed, generally for the vanadate phases [33][34][35][36][37][38][39][40][41][42][43]. Molybdenum oxyfluoride clusters are much less common, although [ The title compound was prepared from the hydrothermal reaction of Cu(CH 3 CO 2 ) 2 ÁH 2 O, MoO 3 , 1,4-butylenediphosphonic acid, and 1,4-bis(2,2 0 :6 0 ,2 00 -terpyridin-4 0 -yl)benzene in the presence of HF [50].…”
