摘要
合成了二种以精氨酸为配体的新型杂多钼酸配合物(C6H15N4O2)4S iW12O401和(C6H15N4O2)8S i2W18O622,并用元素分析、红外光谱及热重分析对其进行表征.对配合物的结构分析表明:配合物中的多阴离子仍保持其Keggin结构或Dawson结构,但其特征振动谱带有一定的蓝移或红移.形成杂多钼酸配合物之后的杂多阴离子S iW12O404-和S i2W18O628-通过静电引力与C6H14N4O2+作用.
The two novel heteropolytungstate complexes （C6H15N4O2）4SiW12O40 and （C6H15N4O2）8Si2W18O62 have been synthesized and characterized by means of elemental analysis, IR spectrum and TG.. For （C6H15 N4O2）4SiW12O40, the structural analysis suggested that heteropoly anion in this compound was reserved its Keggin structure. For （C6 H15N4O2）8Si2 W18O62, the structural analysis suggested that heteropoly anion was reserved its Dawson structure, but the characteristic vibration band had some blue shifts or red shifts. The results show that there are stronge interactions between SiW12O40^4- and Si2W18O62^8- and C6H14N4O2.
