吡啶基丙烯酮配体钴(Ⅱ)及镍(Ⅱ)配合物的合成和结构表征

Synthesis and structural characterization of novel Co(Ⅱ) and Ni(Ⅱ) complexes with pyridyl-propylene-ketone ligand

设计合成具有新颖结构和特殊功能的配合物是当前配位化学研究的热点之一。吡啶基丙烯酮是1种很好的含氮、含氧多功能配体,此配体与金属离子配位可能得到结构新颖、功能奇特的配合物,并可能具有独特的光、电、磁等性质,从而应用于光学材料、磁性和超导材料、催化及药物合成等方面。设计合成了1个吡啶基丙烯酮配体[3-二甲基氨-1-(2-吡啶)-丙烯-1-酮,L],进而得到了2个单核配合物[Co(L)_3](ClO_4)_2(CHCl_3)(H_2O)(配合物1)[Co(Ⅱ)]和[Ni(L)_3](ClO_4)_2(CHCl_3)(H_2O)(配合物2)[Ni(Ⅱ)],并用X-射线单晶衍射表征了其晶体结构。

The design and synthesis with novel structures and special functions is one of the hotspots in coordination chemistry. Pyridinyl ketone is a good multifunctional ligand containing nitrogen and oxygen. Some complexes may be obtained by the coordination of the ligand with metal ions,which can be used in optical materials,magnetic and superconducting materials,catalysis and drug synthesis because of their novel structures and peculiar functions, and unique optical,electrical,magnetic and other properties. A pyridinyl allenone ligan, [3-dimethylammonium-(2-pyridine)-allene-1-ketone,L] was designed and synthesized,and then two monocyte complexes, [Co(L)3](ClO4)(CHCl3)(H2 O)(1)[Co(Ⅱ)] and [Ni(L)3](ClO4)2(CHCl3)(H2 O)(2)[Ni(Ⅱ)] were obtained,and their crystal structures were characterized by X-ray single crystal diffraction.
