本文报导了用PH滴定法及电池电动势法同时研究Ag(Ⅰ)-H_3Ssal及Ag(Ⅰ)—Im—HSsal~-体系的结果.发现在前一个体系中Ag(Ⅰ)与磺酰水杨酸无络合作用,后一个体系中亦无混配络合物生成。但我们在PH=8-8.5的条件下从体系中析出了组成相当于(AgIm_2)_2HSsal的三元化合物,培养了单晶,单晶结构分析的结果说明三元化合物中Ag~+与HSsal~-之间不成键Ag~+只与Im成键,HSsal~-是靠羧基氧与咪唑环上的N原子形成氢键而与AgIm_2~+结合起来的.因此HSsal~-处在三元络合物的外界.这和溶液中不生成混配络合物的研究结果是一致的.
In this paper, the results of the simultaneous determination of Ag (Ⅰ) -H 3 Ssal and Ag (Ⅰ) -Im-HSSal ~ - systems by PH titration and electrokinetic potentiometry were studied. No complexation, the latter system also did not mix with complex formation. However, at pH = 8-8.5, we have precipitated the ternary compound with the equivalent composition of (AgIm_2) _2HSsal from the system. The results of single crystal and single crystal structure analysis show that the Ag ~ + and HSsal ~ - bonds between Ag ~ + and Im only, HSsal ~ - is a combination of AgIm_2 ~ + formed by the hydrogen bond between the carboxyl oxygen and the N atom on the imidazole ring, so HSsal ~ - is in the ternary complex This is in agreement with the findings that no complexing complex was formed in solution.
