The infrared spectra of the oxodiperoxo and triperoxo complexes, (NH4)[VO(O2)2(phen)].2H2O and (NH4)[V(O2)3(phen)].2H2O have been recorded and the observed bands are assigned on the basis of Cs symmetry. Thermogravimetric (TG) and differential thermal analysis (DTA) measurements on these two complexes were also carried out. A detailed mechanism for the mode of thermal decomposition of the two complexes has been given and supported by infrared spectral measurements on the thermal decomposition products. The data obtained agree quite well with the expected structure and indicate that the final thermal decomposition product of these two complexes is V2O5.
已记录了氧代二过氧和三过氧配合物(NH4)[VO(O2)2(phen)].2H2O和(NH4)[V(O2)3(phen)].2H2O的红外光谱，并根据Cs对称性对观察到的谱带进行了归属。还对这两种配合物进行了热重(TG)和差热分析(DTA)测量。给出了这两种配合物热分解模式的详细机理，并通过对热分解产物的红外光谱测量得到了支持。所获得的数据与预期结构相当吻合，表明这两种配合物的最终热分解产物是V2O5。
