减少[(FeCp) 2(联苯)]2 +(2 + 2)被发现是一个化学和elecrochemically可逆的两电子的过程通过循环伏安法在DMF−38 o C 2 e减少新的复杂[(FeCp *) 2(联苯)]2 + (PF 6−)2 (2 + 2 b),使用Na / Hg在四氢呋喃在20 o C ESR-silent稳定蓝抗磁性复杂的2 b,类似于2,而循环voltammogram 2 b 2 +显示亲密的可逆的单电子波。配合物2b经1h、13c核磁共振和穆斯堡尔谱分析证实为36e fe2ii双环己二烯基结构
The reduction of [(FeCp) 2 (biphenyl)] 2+ (2a 2+ ) was found to be a chemically and elecrochemically reversible two-electron process by cyclic voltammetry in DMF at −38 o C. The 2e reduction of the new complex [(FeCp * ) 2 (biphenyl)] 2+ (PF 6 − ) 2 (2b 2+ ), using Na/Hg in THF at 20 o C gives the ESR-silent stable blue diamagnetic complex 2b, analogous to 2a, whereas the cyclic voltammogram of 2b 2+ shows close reversible one-electron waves. The complex 2b was shown by 1 H and 13 C NMR and Mossbauer spectroscopy to have a 36e Fe 2 II bicyclohexadienylidene structure
