The crystal structure of the compound [EDA][Ni(dmit)2]3 (EDA=2-diethylamino-1,3-dithioanylium; dmit=1,3-dithiole-2-thione-4,5-dithiolate)C25H14NNi3S32, has been determined by single crystal X-ray diffraction at 300K. The crystal is triclinic with space group P, a=11.252, b=12.192(2), c=20.055(6) , α=108.127(2), β=106.287(8), γ=90.005(9)°; V=2498.3(3) 3, Z=2, Mr=1530.38, Dc=2.03(2) g/cm3. Final R and Rw values were 0.0603 and 0.0704, respectively. The structure consists of thick layers of stacked Ni(dmit)2 entities separated by EDA cations. This salt shows semiconducting behaviour with room temperature conductivity of 0.2 Scm-1 and activation energy of 0.11 eV. 相似文献
