| Abstract: | The obtention of the crystalline basic carbonate of iron (III) and ammonium, (NH4)4Fe2(OH)4(CO3)3 · 3 H2O, is described, and its formula is established by chemical analysis and infrared spectroscopy. The compound is probably monoclinic, but it was not possible to index with certainty all X-ray reflections. The compound is similar to (NH4)2Fe2(OH)4(CO3)2 · H2O and its infrared spectrum leads to the assumption that in both the CO group is linked in the same fashion. |
