The extent of complexation between silver(I) nitrate and triethylamine and tri-n-butylamine in toluene solutions at 23 °C has been determined by infrared spectroscopy. Both amines produced a mixture of monoamine and diamine silver complexes, and the second stepwise formation constants (K2) are reported. Infrared and atomic absorption experiments on solutions saturated with silver nitrate also yielded
已经通过红外光谱法确定了在23℃下在甲苯溶液中硝酸银(I)与三乙胺和三正丁胺之间的络合程度。两种胺均生成单胺和二胺银配合物的混合物,并且报告了第二个逐步形成常数(K 2)。在用硝酸银饱和的溶液上进行的红外和原子吸收实验也得出了硝酸银在甲苯中的第一形成常数(K 1)和溶解度乘积(K s)的形式值。结果表明,Et 3 N在甲苯中与银(I)的配位比Bu 3 n更强。N.发现甲苯中的K 1值是质子和偶极非质子溶剂的4–5幂,高10倍,而K 2的值较小。给出了结构和溶剂化的原因来解释这些结果。
