摘要:
通过溶液法合成一个二维Co(Ⅱ)配合物Co(pmida)(pica)(H2pmida=2-氨甲基-N,N’-二乙酸吡啶, Hpica=2-吡啶甲酸), 并采用X射线单晶衍射法、红外光谱和电子光谱对配合物进行表征. 结果表明:在标题配合物中, 中心原子Co(Ⅱ)呈扭曲的N3O3八面体配位构型;晶体相邻分子间存在C-H…π边对面作用和π-π相互作用, 使得沿b轴方向看, 配合物形成两条平行的波浪形链条. 运用Gaussian 03程序, 以配合
Abstract:
A new metal coordination complex Co(pmida)(pica)(H2pmida=N-(2-pyridylmethyl)iminodiacetic acid, Hpica=2-picolinic acid), has been synthesized by solution method and characterized by X-ray single crystal diffraction, FTIR and electron spectroscopy. The cobalt atom in the title complex is coordinated with two pyridine nitrogen atoms one amidogen nitrogen atom and three carbonyl oxygen atoms forming a distorted octanhedral arangement and four chelating five membered rings. There are two chain structures through the C-H…π and π-π interactions in the neighboring ligands. The ab-initio Gaussian 03 calculations with Hartree-Fork method showed that the results keep in line with electronic spectra.
