Hydrothermal Synthesis and Structure of [(C2H5)4N][(VO)3(OH)(H2O)(C2H5PO3)3].cntdot.H2O. An Inorganic-Organic Polymer Exhibiting Undulating V/P/O Layers and Interlamellar Organic Templates

Syntheses and Properties of New Layered Alkali-Metal/Ammonium Vanadium(V) Methylphosphonates: M(VO2)3(PO3CH3)2 (M = NH4, K, Rb, Tl). Single-Crystal Structures of K(VO2)3(PO3CH3)2 and NH4(VO2)3(PO3CH3)2

“…The effect of the cation is probably small, since the (VO 2 ) 3 (PO 3 CH 3 ) 2 geometries in K(VO 2 ) 3 (PO 3 CH 3 ) 2 and NH 4 (VO 2 ) 3 (PO 3 CH 3 ) 2 are virtually identical. Other layered vanadium organophosphonates based on sheet motifs involving both V−O−V‘ and V−O−P bonds have been described elsewhere. , …”

“…[33] In this area, the Zubieta group has also obtainedaseries of seminalc ontributions and brilliant achievements. [34][35][36][37][38][39][40][41][42][43][44] Finally,a nd more importantly,t he variable valences of V( + IV/ + V) may modify and improvec atalytic properties. Someo pen-framework compounds containing V 4 + /V 5 + have displayed excellent catalytic activities for the selectiveo xidation of the benzylic CÀHb ond, whichi ss till an important and challenging project in green chemistry up to the present.…”

“…Secondly, the flexible coordination behaviors of Cu 2+ and V 4+ /V 5+ cations provide greater opportunities for the rational design of new structures with interesting architectures . In this area, the Zubieta group has also obtained a series of seminal contributions and brilliant achievements . Finally, and more importantly, the variable valences of V (+IV/+V) may modify and improve catalytic properties.…”

Structural Variability of the Vanadium−Organodiphosphonate System: Hydrothermal Syntheses and Structural Characterizations of One-Dimensional, Two-Dimensional, and Three-Dimensional Phases

“…As an approach to the design of selective oxidation catalysts, − we have sought to combine the modification of organic substituents of the organophosphonate, the thermal stability and reactivity of transition metal oxide units, the interplay of hydrophobic and hydrophilic domains, and substrate-specific recognition and incipient coordinative unsaturation of the vanadium sites. Based on our observations of major structural modifications in the layered VORPO 3 phases by substituent modification and/or introduction of appropriate templates, − investigations of the chemistry of the vanadium−organodiphosphonate system, V{R(PO 3 ) 2 H 4 - n } n - , in the hydrothermal reaction domain were initiated.…”
