| 英文摘要 | A nickel-nickel-bonded complex, [{Ni(μ-L·-)}2] (1; L=[(2,6-iPr2C6H3)NC(Me)]2), was synthesized from reduction of the LNiBr2 precursor by sodium metal. Further controllable reduction of 1 with 1.0, 2.0 and 3.0 equiv of Na, respectively, afforded the singly, doubly, and triply reduced compounds [Na(DME)3]·[{Ni(μ-L·-)}2](2; DME=1,2-dimethoxyethane), [Na-(Et2O)]Na[(L·-)Ni-NiL2-] (3), and [Na(Et2O)]2Na[L2-Ni-NiL2-] (4). Here L represents the neutral ligand, L·- denotes its radical monoanion, and L2- is the dianion. All of the four compounds feature a short Ni-Ni bond from 2.2957(6) to 2.4649(8) Ǻ. Interestingly, they display two different structures: the perpendicular (1 and 2) and the coaxial (3 and 4) structure, in which the metal-metal bond axis is perpendicular to or collinear with the axes of the adiimine ligands, respectively. The electronic structures, Ni-Ni bonding nature, and energetic comparisons of the two structure types were investigated by DFT computations. |
