摘要
用斜率法、等克分子比法和饱和容量法确定了亚砜ＫＳＯ－ｐｄ（Ⅱ）萃合物组成（Ｐｄ）／（ＫＳＯ）＝１：１，利用远红外光谱、紫外、可见光谱及萃合物元素分析确定了萃合物结构为桥式双核结构ｔｒａｎｓ－（ＰｄＬＣｌ＿２）＿２。借助于萃合物红外光谱分析确定亚砜ＫＳＯ分子中硫氧原子均能与Ｐｄ（Ⅱ）配位。
Three methods, slop method, equilimolecular ratio method, and saturated volume method,were used to determine the composition of sulfoxidePd(Ⅱ)complex,and it was indicated that Pd/KSO equals to 1:1 in the KSO-Pd(Ⅱ)complex when Pd(Ⅱ)was extracted by KSO. The far-infrared spectrum, visible spectrum, and violet spectrum of KSO-Pd(Ⅱ)complex show that the extractive exists as the structure of chloride-bridged binuclear trans-Pd LCl_2)_2. Infrared spectrum of KSO-Pd(Ⅱ)complex proves that both sulfur and oxygen atom in KSO can coordinated to Pd(Ⅱ).
