Structural and Chemical Effects of the Surrounding Cations and Coexisting Compounds on [M(α-PW₁₁O₃₉)₂]ⁿ.

ABSTRACT: The effects of countercations and coexisting compounds on the molecular structure of the [M(α-PW₁₁O₃₉)₂] ^n- polyanion were analyzed in terms of the repulsion and twisting of two [α-PW₁₁O₃₉]^7- units. More specifically, it was found that two [α-PW₁₁O₃₉]^7- ions approached one another upon reducing the ionic radius of M in [M(α-PW₁₁O₃₉)₂] ^n-. The interactive twisting of the [α-PW₁₁O₃₉]^7- units prevented mutual repulsion of the units containing terminal O atoms, and the tendency for approach and twisting of the [α-PW₁₁O₃₉]^7- units varied as a function of the type o
