| 英文摘要 | A series of sodium and magnesium complexes with alpha-diimine ligands, [na-2(l-ipr)(et2o)](2) (1, l-ipr = [(2,6-(pr2c6h3)-pr-i)n(me)c](2)), [na-2(l-mes)(solv)(2)](2) (l-mes = [(2,4,6-me3c6h3)n(me)c](2), 2a, solv = et2o; 2b, solv = thf), [na-4(l-et)(2)](n) (3, l-et = [(2,6-et2c6h3)n(me)c](2)), and [mg(l-mes)(thf)(3)] (4), have been synthesized by reduction of the diimine ligands with sodium or magnesium metal. single-crystal x-ray diffraction analysis revealed that the sodium complexes have a 2:1 [na2l] unit that aggregates to dimeric (1, 2a, 2b) or polymeric (3) structures, while the magnesium complex (4) shows a monomeric 1:1 structure. in all compounds 1-4, the ligand is doubly reduced to a dianion. the two na+ ions in 1, 2a, 2b, and 3 show different coordination modes, one of which is chelated by the n donors of a ligand with supplementary na-c bonds to the phenyl ring of another ligand within the [na2l](2) dimer, while the other is bonded by the central c2n2 core of the ligand and solvent molecules (1, 2a, and 2b). compound 3 displays a novel three-dimensional network. the mg2+ ion in 4 is coordinated by a ligand molecule and three thf molecules. density functional theory (dft) computations on the sodium and magnesium complexes 1 and 4 confirmed their electronic structures and the dianionic character of the ligands. |
