The first charge transfer salt based on non-dimerized [BEDO-TTF]{sup +} monocationic radical (BEDO-TTF=bis(ethylenedioxy)tetrathiafulvalene) associated with [Mo{sub 6}Br{sub 14}]{sup 2-} cluster anions has been synthesized by conventional electro-oxidation and characterized by single crystal X-ray diffraction, UV-VIS-NIR absorption and magnetic susceptibility measurements. (BEDO-TTF){sub 2}Mo{sub 6}Br{sub 14}(PhCN){sub 4} crystallizes in the monoclinic system, space group P2{sub 1}/n, a=10.414(4)A, b=21.711(7)A, c=15.958(5)A, {beta}=93.65(3){sup o}, V=3601(2)A{sup 3}, Z=2, R{sub 1}=0.0578, wR{sub 2}=0.0731. The structure of this hybrid compound is built up from a [BEDO-TTF]{sup +} and PhCN (benzonitrile) organic framework in which are hosted the [Mo{sub 6}Br{sub 14}]{sup 2-} inorganic cluster units. It results in non- dimerized [BEDO-TTF]{sup +} cations that exhibit a paramagnetic behavior characteristic of one unpaired electron.
