钴在4-methyl-N-(2-pyridylmethyl)benzenesulfonamide(HL，1)乙腈溶液中的电氧化生成化合物[CoIL2](2)或[CoIIIL2Lo](3)。在电解相中加入2，2‘-联吡啶(Bipy)或1，10-邻菲咯啉(Phen)，得到[CoIIL2bipy](4)和[CoIIL2phen](5)。用X射线衍射法测定了HL(1)、[CoIIL2](2)和[CoIIIL2Lo](3)的晶体结构。化合物[CoIIL2]是单核的，具有扭曲的四面体[CoN4]几何构型，每个酰胺配体充当阴离子(NamideNpy)双齿配体。在单体络合物[CoIL2LO]中，钴原子处于扭曲的八面体[CoN6]环境中，该环境由两个L−阴离子配体的酰胺和吡啶氮原子以及一个新的阴离子配体LO的氨基两个氮原子定义，该阴离子配体是由三个乙腈分子在电解槽中三聚而成。讨论了化合物的电子光谱、红外光谱和原子吸收光谱。(Wiley-VCH Verlag GmbH，69451温海姆，德国，2002年)
Electrochemical oxidation of cobalt in a solution of 4-methyl-N-(2-pyridylmethyl)benzenesulfonamide (HL, 1) in acetonitrile afforded the compounds [CoIIL2] (2) or [CoIIIL2Lo] (3). When 2,2′-bipyridine (bipy) or 1,10-phenanthroline (phen) was added to the electrolytic phase, [CoIIL2bipy] (4) and [CoIIL2phen] (5) were obtained. The crystal structures of HL (1), [CoIIL2] (2) and [CoIIIL2Lo] (3) were determined by X-ray diffraction techniques. The compound [CoIIL2] is mononuclear and has a distorted tetrahedral [CoN4] geometry, with each amide ligand acting as an anionic (NamideNpy) bidentate ligand. In the monomeric complex [CoIIIL2Lo] the cobalt atom is in a distorted octahedral [CoN6] environment defined by the amide and pyridyl nitrogen atoms of two L− anionic ligands and the two nitrogen atoms of the NH groups of a new anionic ligand Lo, which is formed by trimerisation of three acetonitrile molecules in the electrolytic cell. The electronic, IR and FAB spectra of the compounds are discussed. (© Wiley-VCH Verlag GmbH, 69451 Weinheim, Germany, 2002)
