First tetrathiafulvalene (TTF) cation‐radical salt containing the inorganic polyoxometalate β‐[Mo8O26]4⊖
Source abstract
Abstract
Polyoxometalate complexes are attractive precursors for the preparation of new radical‐ion salts based on π‐electron organic donors of the tetrathiafulvalene (TTF) type, the most widely used molecules in the synthesis of organic conductors and superconductors. The well‐defined sizes and shapes of polyoxometalates, as well as their ability to undergo multiple electron reduction, may induce novel structural and electronic properties in the organic component. The preparation and the X‐ray crystal structure analysis of the new compound (TTF)7Mo8O26 are presented.

Triclinic P1 a = 12.146(9) Å b= 13.367(7) Å c=14.361(6) Å α = 84.61(4)° β =79.13(6)° γ = 63.67(7)° V= 2052 Å3 Z= 1 (dcalc= 2.115 g cm−3); Moκαradiation (λ = 0.71073 Å μ = 19.06 cm−1). Data were collected in the range 2 ≤ 2θ < 50° with the θ–2θ scan mode. The structure was solved by direct methods and successive Fourier difference synthesis. Refinement of 300 variables with anisotropic thermal parameters (for only Mo and S atoms) gave R = 0.079 andRω= 0.095 by using 2254 absorption corrected reflections withI< 2σ (I).
