本文首次报道N-氧化吡啶-2-甲醛希夫碱配体与贵金属Au(Ⅲ)和Pt(Ⅳ)的配盐[(C_7H_8N_4O_2)_2H][LAuCl_4](1)和[C_7H_8N_4O_2)_2H]_2[PtCl_6]·6H_2O)(2)的合成,并使用元素分析、红外、紫外、荧光光谱、摩尔电导的手段进行结构表征;并报道配盐1的晶体结构,配盐1的晶体学数据:C2/c,a=19.723(2)人,b=7.510(1)入, c=16.414(5)人,夕:=115.73(1)°,R=0.037.晶体结构研究表明:配盐是由阳、阴离子缔合而成的中心对称的配盐分子。

This paper first reports the synthesis of the complexes of novel metal of Au(Ⅲ) and Pt (Ⅳ) with schiff base ligand of N-oxide -2-picolinaldehyde semicarbazide . The complexes were characterized by elemental analysis ,IR,UV and fluroescence spectra and molar conductance. A single crystal structure of the complex Au(Ⅱ) is also reported.The crystal data: C2/c,a = 19. 723(2),b=7. 510(1),c=16. 414(5) (?), β=115. 73(1)°R=0. 037. The crystal structure study indicates that the complex is a centrosym-metric associated complex by anion and cation.
