Ferric ammonium oxalate is a green crystalline, solid with a granular or salt-like appearance. Color
depends on level of iron present
Ammonium iron(III) oxalate trihydrate is used in the preparation of Langmuir-Blodgett magnetic thin films. It is also involved in the production of blueprint paper.
Ammonium ferric oxalate trihydrate decomposes completely at 275°C giving Fe2O3 and has been investigated by thermogravimetry and differential thermal analysis.
Ferric ammonium oxalate is used in
photography and making blueprints

Crystallise it from hot water (0.5mL/g). [Beilstein 3 III 1103.]
Incompatible with oxidizers (chlorates,
nitrates, peroxides, permanganates, perchlorates, chlorine,
bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases,
strong acids, oxoacids, epoxides. Strong oxidizers may cause
release of toxic phosphorus oxides. Organophosphates, in the
presence of strong reducing agents such as hydrides, may
form highly toxic and flammable phosphine gas. Keep away
from alkaline materials.
