Its crystal structure and magnetic property were determined and investigated. Discussion about the molecule packing in crystal and the macroscopic magnetism was also presented, in combination with computing study of the spatial distribution over the molecule.展开更多
Several precursors of organic conductors based on metal-(dmit)2 anion complex withcarbonium as counter cations were first synthesize Some of them exhibit greatly increased conductivities upon iodine doping.
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)C 25 H 14 NNi 3S 32 , has been determined by single...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)C 25 H 14 NNi 3S 32 , has been determined by single crystal X ray diffraction at 300K. The crystal is triclinic with space group P1, 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, M r=1530.38, D c =2.03(2) g/cm 3. Final R and R w 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.展开更多
Reaction of C-60 with DL-valine and cyclohexanone in refluxing chlorobenzene under N-2 yields three [60]fulleropyrrolidine derivatives (mono-, bis- and triadduct) which are characterised on the basis of spectroscopies...Reaction of C-60 with DL-valine and cyclohexanone in refluxing chlorobenzene under N-2 yields three [60]fulleropyrrolidine derivatives (mono-, bis- and triadduct) which are characterised on the basis of spectroscopies and cyclic voltammetry. It is found that the ratio of the three products greatly depends on the reaction conditions.展开更多
