The Anderson–Evans polyoxometalate: From inorganic building blocks via hybrid organic–inorganic structures to tomorrows “Bio-POM”

“…A first classification [1] divides the Anderson-Evans structure into two types: the non−protonated A−type with central heteroatoms in high oxidation states with the general formula [X n+ M 6 O 24 ] (12-n)-(X = e.g. Te VI [40], I VII [41]) and the protonated B−type with heteroatoms in low oxidation states and the general formula [X n+ (OH) 6 M 6 O 18 ] (6-n)-(X = e.g. Cr III [42], Fe III [43]).…”

Computational Study of Solvent Effects and the Vibrational Spectra of Anderson Polyoxometalates

“…Bond orders were calculated by using the definition proposed by Mayer [19] respectively using the MAYER program. [20] Results and Discussion 6À from that study and using the additional methods used here and for [IMo 6 O 24 ] 5À together with the available experimentally determined distances [22,23] at each of the computational levels used for the vibrational modelling. The vibrational analyses reported below confirm that these ions have full D 3d symmetry respectively in the gas phase, as assumed in our earlier computational studies of the structures of these anions [21] as well as in solution.…”

A novel chain-like polymer constructed from heteropolyanions covalently linked by lanthanide cations: (C 5 H 9 NO 2 ) 2 [La(H 2 O) 7 CrMo 6 H 6 O 24 ] · 11H 2 O (Proline=C 5 H 9 NO 2 )

“…The structure of [CrMo 6 H 6 O 24 ] 3À is a typical Anderson anion similar to the reported Anderson structure[17]. The Mo atoms closely approximate a regular planar hexagonal configuration with the Cr located in its center.…”
