摘要: The crystal structure of ferrinatrite, Na3[Fe(SO4)3]·3H2O, was refined based on a new single-crystal X-ray diffraction experiment sample from the type locality Sierra Gorda, Chile. data allowed H to be successfully located and H-bonding system defined. Infrared Raman spectra are presented discussed for this compound basis structure. Oacceptor···H–Odonor bond distances determined refinement agree well with geometric correlation obtained spectroscopic data. thermal stability dehydration process ferrinatrite investigated by in situ high temperature (HT) synchrotron powder diffraction, Fourier transform infrared spectroscopies.
