The obtention of the crystalline basic carbonate of iron (III) and ammonium, (NH 4 ) 4 Fe 2 (OH) 4 (CO 3 ) 3 · 3 H 2 O, 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 (NH 4 ) 2 Fe 2 (OH) 4 (CO 3 ) 2 · H 2 O and its infrared spectrum leads to the assumption that in both the CO 3 2−group is linked in the same fashion.
