钨、钼羧酸合过氧配合物的合成及性质研究

Study on the Synthesis and Preparation of Tungsten(Ⅳ)and Molybdenum(Ⅳ)Carboxylato Peroxo Complexes

引进能和钨、钼形成稳定的五元环的羧酸类配体（即：草酸、酒石酸、柠檬酸、苹果酸等），制得了十种新的稳定的钨、钼羧酸合过氧配合物；（ＮＨ４）２［ＭＯ（０２）２（Ｃ２Ｏ４）］（Ｍ＝Ｗ或Ｍｏ）；（ＮＨ４）［ＭＯ（Ｏ２）２Ｌ］·ＺＨ２Ｏ（Ｌ＝酒石酸根、柠檬酸根、苹果酸根）和（ＮＨ４）４［Ｍ２Ｏ２（Ｏ２）４（Ｃ２Ｈ２Ｏ５）］４Ｈ２Ｏ测定了这些过氧配合物固体的Ｒａｍａｎ和ＩＲ光谱以及水溶液的Ｒａｍａｎ光谱，并对配位结构进行了探讨，研究了这些过氧配合物的热稳定性．

n this paper,synthesis method of ten new tungsten (Ⅳ) and molybdenum (Ⅵ)peroxo complexes (NH4),[MO(O2)(C2O4)] (M=W or Mo),(NH4)2[MO (O2)2L].2H2O(M=W or Mo,L=tartrate,citrate or palate) and (NH4)4[M2O2(O2)4(C4H2O6)].4H2O(M=W or Mo) is reported.Raman and iR spectra of the solid complexes and Raman spectra of their aqueous solutions have been measured, and these spectra are used to suggest the structure of the species in the solid state and solution.Thermal stability of the peroxo complexes has also been studied.
