Abstract:
This work, consist to the study of the solid composition with dual character organicinorganic permits us to conclude the hybrid character of the given materials. This one
appears in the structural organizations and the electronic properties observed.
A part of this memory is about the preparation of new polyoxométallates by
hydrothermal technic. We present three new compounds (TTF)8[Mo6O19]2(CH3CN),
(C14H16N2)2 (C14H17N2)2(C14H18N2)[β-Mo8O26] and H[MoO3], exhibited a character
semi-conductor confirmed by structural, spectroscopic and electro-chemical
characterizations.
To explain the electronic properties of different isopolyoxometalates. we have showed
the correlation between the structural particularities of each one of isomers, and their
electronic proprieties.
The relation between the different values of the gap with the geometric structure
observed was calculated by the functional of the density using GGA and LDA
approximations.
