摘要：

The crystal structure of [Fe(H(2)isoor)(2)(H2O)(2)]. 2H(2)O has been solved by single-crystal X-ray diffractometry. Thermogravimetric analysis shows simultaneous loss of all water molecules between 120 and 266 degrees C, followed immediately by a rapid degradation of the compound. A comparative analysis of the Raman spectra of the complex with that of free iso-orotic acid allowed a straightforward assignment of the vibrations of the ligand groups involved in coordination. The Fe-57 Mossbauer spectrum of the complex confirms the presence of a high-spin Fe-II ion and the distortion of the octahedral Fe-II environment.
