Inorganic–organic hybrid materials: synthesis and crystal structures of the layered solids [{M(H2O)(2,2′-bipy)}V2O6] (M=Co, Ni)

Synthesis, structure and fluorescent studies of novel uranium coordination polymers in the pyridinedicarboxylic acid system

“…Hybrid materials have shown promise in a vast array of applications such as catalysis, gas storage, ion exchange, magnetic materials, optics and separations. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15] Much effort has been geared towards the design of multi-dimensional hybrid architectures by taking advantage of the favored geometry of the local metal center in addition to utilizing the functionalities and sterics of the organic components through which the metal centers are linked. 16 Although the efforts to produce transition metal-based coordination polymers have been quite extensive, [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33] the synthesis of actinide-based coordination polymers has been a less examined area.…”

Solid-State Structural Characterization of a Rigid Framework of Lacunary Heteropolyniobates

“…[3][4][5] The tendency of the niobates toward these linked cluster compounds is perhaps a mechanism to stabilize the highly charged clusters because the linkages always involve positively charged species (i.e., [Ti 2 O 2 ] 4+ and [Nb 2 O 2 ] 6+ ). 3 Alternatively, the predominance of linked clusters observed in polyoxoniobate chemistry may simply be favored by hydrothermal processing, as has been observed in hydrothermal synthesis of inorganic and organicinorganic linked frameworks of heteropolyvanadates and -molybdates [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] and to a lesser extent the heteropolytungstates. 24 In either case, frameworks of linked clusters currently dominate heteropolyniobate chemistry, and hydrothermal synthesis is the only route thus far that has produced these clusters in sufficient yield and purity necessary for isolation and characterization.…”

CoV2O6–V2O5 Coupled with Porous N-Doped Reduced Graphene Oxide Composite as a Highly Efficient Electrocatalyst for Oxygen Evolution

“…As a consequence, the development of a simple method to prepare precursors with stable and uniform structure for use as a perfect platform to gain bimetallic oxide catalysts is a challenge for electrochemistry. Polyoxovanadates (POVs), 33 as a subfamily of polyoxometalates (POMs), have precise architectures that guarantee the further synthesis of the target compound with quantitative metal atomic ratio. Moreover, polyoxovanadates consisting of different metal atoms have no need to introduce new material source, which greatly avoids the complexity of the system.…”
