For the trinickel metal string complex 1, the central Ni2+ ion is square planar with four short Ni—Namido distances at a range of 1.879 - 1.894 Å, indicating a low-spin (S = 0) square planar Ni2+ configuration. Two terminal Ni2+ ions are in a square pyramidal environment with average Ni—Npyridine distances in the range of 2.069 - 2.095 Å. The averaged Ni—Ni distances in 1 are 2.364 Å. The magnetic susceptibility measurements in the solid state show that both complex 1 and 2 have an antiferromagnetic interaction. The electrochemistry of complex 2 is investigated by cyclic voltammetry. It exhibits one electrochemically reversible one-electron redox process at E1/2 = 0.12 V in CH2Cl2 containing 0.1 M TBAP. The E1/2 = 0.12 V is described as the one-electron reduction for [Ru2]6+/[Ru2]5+ process. 彭旭明 2016 學位論文 ; thesis 117 zh-TW |
