Decavanadates: a building-block for supramolecular assemblies

Hetero and lacunary polyoxovanadate chemistry: Synthesis, reactivity and structural aspects

“…To obtain information about differences in the basicity of the surface oxygen atoms, experimental electrostatic potentials on the surface of the non-protonated form were estimated [62]. The crystal packing of decavanadates exhibits four types of distinct interaction pattern, monomers, dimers, and 1D and 2D arrays, through a variety of hydrogen bond interactions [63,64]. In aqueous solution, decavanadate species may be in equilibrium with mononuclear species and substitution of some of the vanadium units Such metals are unlikely to be found at peripheral positions due to the required presence of a terminal oxo group, which would be unstable to hydrolysis.…”

Synthesis of Metforminium(2+) Decavanadates – Crystal Structures and Solid‐State Characterization

“…Although 2 and 3 crystallize in the same centrosymmetric space group as 1, a remarkable difference for 2 and 3 is that the [V 10 O 28 ] 6-anion is placed on an inversion center, which is not the case for 1. modulation of the structures and properties of the new hybrid materials on the basis of electrostatic and hydrogenbond interactions. [9] Interestingly, inorganic and organic decavanadates have been used as building blocks [21] to generate supramolecular frameworks that exhibit wide structural diversity in one, two, or three dimensions (e.g., chains, [13,20,22] layers, [14,16,23] channels, [24] or 3D networks). [10,14,17,18] The formation of the supramolecular structure is strongly dependent on the solvent, [25] pH value, ionic strength, temperature, and nature of the counterions [13][14][15][16][17][18][19][20][21]26] used in the synthesis.…”

In the last decade, the basicity of the oxygen atoms in the decavanadate cluster has been established, [27,28] and the type and strength of hydrogen-bond interactions for the seven types of oxygen atoms in the decavanadate cage with a range of cations and organic molecules has been reviewed recently.…”

Conductive Supramolecular Architecture Constructed from Polyoxovanadate Cluster and Heterocyclic Surfactant

“…Among several POMs, a polyoxovanadate such as decavanadate ([V 10 O 28 ] 6− , V 10 , Figure 1), tends to be associated with protons [56][57][58][59][60][61]. Therefore, polyoxovanadate-surfactant hybrid crystals are promising as proton-conducting materials, and anhydrous proton conductivity has been evaluated for the V 10 hybrid crystals comprising decyltrimethylammonium ([(C 10 H 21 )N(CH 3 ) 3 ] + , C 10 ) surfactant [47].…”
