Английская Википедия:Iron(II) citrate
Ferrous citrate, also known as iron(II) citrate or iron(2+) citrate, describes coordination complexes containing citrate anions with Fe2+ formed in aqueous solution. Although a number of complexes are possible (or even likely), only one complex has been crystallized. That complex is the coordination polymer with the formula [Fe(H2O)6]2+{[Fe(C6H5O7)(H2O)]−}2.2H2O, where C6H5O73- is HOC(CH2CO2−)2(CO2−, i.e., the triple conjugate base of citric acid wherein the three carboxylic acid groups are ionized.[1] Ferrous citrates are all paramagnetic, reflecting the weak crystal field of the carboxylate ligands.[2]
Ferrous citrates are produced by treating disodium citrate Шаблон:Chem with sources of iron(II) aquo complexes, such as iron(II) sulfate.[3][4] Ferrous citrates are all highly unstable in air, converting to ferric citrates.
It is a nutrient supplement approved by the FDA.[5][6]
