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-NH_2-p-R-C_6H_4OH,R=-C(CH_3)_3、-H、-Cl、-NO_2),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.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.
