Five of their single crystals were obtained and their structures were determined by X-ray diffraction. By comparison, it was found that dithiocabamate complexes often formed an exactly planar MS4 unit, such as [Mo(R2dtc)2]; and also formed a special MS 5 unit, such as [Cu2(R2dtc)4], the copper atom lies in a distorted square-pyramidal environment.Four kinds of heteropoly acids were prepared and characterized; a series of solid superacid catalyst of supported heteropoly acid were prepared and characterized; regioselectivites of chlorobenzene mononitration with nitric acid with different heteropoly acid on different supports and reaction conditions have been investigated.

培养并解析了5个该类配合物的单晶结构，通过比较，发现二硫代氨基甲酸盐与过渡金属容易形成四配位结构，金属原子与4个硫原子共平面，比如二乙基二硫代氨基甲酸钼；也能形成比较特殊的五配位结构，比如二乙基二硫代氨基甲酸双核铜，Cu原子与5个S原子相连，处于一个变形的四方锥结构的配位环境。

The smaller the electronegativity is, the higher oxidation activity is. Thus phosphomolybdic acid shows better catalytic oxidation activity than phosphotungstic acid.

由于磷钨酸中的钨可以脱出并少量沉积到催化剂表面，而且从电负性来说Mo-O的键能小于W-O，键能小的杂多酸有较强的氧化性，所以钼系杂多酸催化活性要好于钨系杂多酸。
