✦ Synopsis
The first charge transfer salt based on non-dimerized [BEDO-TTF] + monocationic radical (BEDO-TTF ¼ bis(ethylenedioxy)tetrathiafulvalene) associated with [Mo 6 Br 14 ] 2À 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) 2 Mo 6 Br 14 (PhCN) 4 crystallizes in the monoclinic system, space group P2 1 /n, a ¼ 10.414(4) A ˚, b ¼ 21.711(7) A ˚, c ¼ 15.958(5) A ˚, b ¼ 93.65(3)1, V ¼ 3601(2) A ˚3, Z ¼ 2, R 1 ¼ 0:0578, wR 2 ¼ 0:0731. The structure of this hybrid compound is built up from a [BEDO-TTF] + and PhCN (benzonitrile) organic framework in which are hosted the [Mo 6 Br 14 ] 2À inorganic cluster units. It results in non-dimerized [BEDO-TTF] + cations that exhibit a paramagnetic behavior characteristic of one unpaired electron.
