本文采用水热反应条件 ,合成得到一种新型的含五价钼原子的杂多化合物 :(NH3CH2 CH2 NH3) 7H2[NaMo1 2 O30 (PO4 ) 2 (HPO4 ) 5(H2 PO4 ) ]·7H2 O ,在晶体结构测定的基础上对其进行红外、拉曼和紫外 可见漫反射光谱研究。结果表明 :较长的Mo(Ⅴ )—O键键长和分子内大量的氢键造成化合物红外光谱特征的红移。
In this paper, a new type of heteropoly compound containing pentavalent molybdenum atoms was synthesized by hydrothermal reaction conditions: (NH3CH2CH2NH3) 7H2 [NaMo1 2 O30 (PO4) 2 (HPO4) 5 (H2 PO4)] 7H2O, Based on the crystal structure measurement, the infrared, Raman and UV-visible diffuse reflectance spectra were studied. The results show that the longer Mo (Ⅴ) -O bond length and the intramolecular hydrogen bond result in the red shift of the IR spectra of the compounds.
