transfer; TTF moiety in F 4 TCNQ salt was partially oxidized but that of DDQ salt was completely oxidized. The radical cation salts of [Cu II (saeTTF) 2 ] with PF 6 - anion was also obtained in 1:1 donor and anion ratio by electrocrystallization. The donor and anion ratio indicates that the oxidation state of TTF moieties in the radical salt, [Cu II (saeTTF) 2 ]PF 6 , was partial oxidation state.
已经合成了具有席夫碱型配位位点的新型 TTF 基配体(TTF = 四硫富瓦烯):4,5-双(4-水杨基亚氨基苯基)-4',5'-乙二硫基-TTF(1a)、4,5-双(4-picolinideneiminophenyl)-4',5'-ethylenedithio-TTF (1b) 和 4-(2-salicylideneiminoethylthio)-5-methyl-4',5'-ethylenedithio-TTF (Hsae-TTF)。1a 的 X 射线晶体学显示,1a 在配位点周围具有刚性结构,这阻止了它形成金属配合物。另一方面,由于烷基链间隔,Hsae-TTF配体在其配位点周围具有柔韧性,并与Ni(II)和Cu(II)离子形成单核配合物,[M II (saeTTF) 2 ] (M II =Ni (II) 和铜 (II))。[M II (saeTTF) 2 ] 中的金属离子具有方形平面配位结构,具有两个基于
