Synthesis and properties of BEDSe-TTF
We report the synthesis and properties of the ..pi..-electron donor molecule 4,5:4',5'-bis(ethylene-1,2-diseleno)-tetrathiafulvalene (BEDSe-TTF) as well as the properties of a novel charge-transfer (C-T) salt derived from it. BEDSe-TTF was obtained in a 25% overall yield by a three-step reaction starting from the organometallic complex, bis(tetrabutylammonium)-bis(2-thione-1,3-dithiole-4,5-diselenolato)nickelate(II). A single crystal x-ray structure determination of BEDSe-TTF showed it to be monoclinic, P2/sub 1//n, with a = 6.842(2), b = 14.047(5), c = 16.094(5)/angstrom/ and ..beta.. = 94.49(3)/degree/ having a unit cell volume of 1542/angstrom//sup 3/ and four molecules per unit cell. Electrochemical oxidation of BDESe-TTF gave single crystals of BEDSe-TTF/sup +/I/sub 3//sup -/. The structure of this 1:1 C-T salt was also monoclinic, P2/sub 1//n, with a = 12.503, b = 10.592, c = 15.842 /angstrom/ and ..beta.. = 100.12/degree/ having a unit cell volume of 2065.4 /angstrom//sup 3/ and four molecules per unit cell.
