| 摘要: 以2,5-噻吩二甲醛与一系列对位取代的邻氨基苯酚(o-NH2-p-R-C6H4OH,R=-C(CH3)3、-H、-Cl、-NO2),经缩合所得到的希夫碱为配体,合成了Ni(Ⅱ)、Co(Ⅱ)、Pb(Ⅱ)和Ag(Ⅰ)的配合物,通过元素分析、差热-热重分析、摩尔电导、磁化率、红外和紫外-可见光谱以及乙醇溶液中Pb(Ⅱ)配合物表观稳定常数的测定,研究了配合物的组成、结构和性质. |

| Abstract: A series of Ni(Ⅱ), Co(Ⅱ), Pb(Ⅱ) and Ag(I) complexes of Schiff bases, derived from condensation of 2,5-thiophenedicarbaldehyde with o-amino-p-phenol (R =-C(CH3)3,-H,-Cl,-NO2), were prepared and characterized by means of elemental analyses, differential thermal-thermogravimetric analyses, electrical conductances, magnetic susceptibility, IR and UV-Visible spectra. Apparent formation constant of Pb(Ⅱ) complexes were determined in alcoholic solution. The relationship between composition, properties and structures were studied. |
