Iron(II) oxalate dihydrate

Description:
Iron(II) oxalate dihydrate, with the chemical formula C2FeO4·2H2O, is a coordination compound that features iron in the +2 oxidation state coordinated with oxalate ions. This compound typically appears as a greenish or yellowish crystalline solid. It is soluble in water, and its solubility can be influenced by pH and temperature. Iron(II) oxalate dihydrate is often used in various applications, including as a precursor in the synthesis of iron-based materials and in analytical chemistry for the determination of oxalate ions. The dihydrate form indicates that it contains two molecules of water for each formula unit, which can affect its stability and reactivity. When heated, it can decompose, releasing carbon dioxide and water, and potentially forming iron oxides. As with many iron compounds, it may exhibit paramagnetic properties due to the presence of unpaired electrons in the d-orbitals of iron. Safety precautions should be taken when handling this compound, as it can be harmful if ingested or inhaled.
