Solutions of this solid have been used in Europe as an antidote to cyanide poisoning.[1] It is a derivative of the (non-natural) amino acid ethylenediaminetetraacetate. StructureThe compound is polymeric in the crystalline form. Half of the Co2+ ions are bound to the EDTA2− and the other Co2+ ions are bound to four water ligands as well as carboxylate ligands on the [Co(EDTA)]2− entity.[2] In aqueous solution, depolymerization occurs to give [Co(EDTA)]2− and [Co(H2O)6]2+ ions, each of which is kinetically labile and has a high affinity for cyanide. Related compoundsOxidation of [Co(II)(EDTA)]2− gives [Co(III)(EDTA)]−, which is so kinetically inert that it can be resolved optically.[3] References1. ^{{cite journal |author=Pickering WG |title=Cyanide toxicity and the hazards of dicobalt edetate |journal=Br Med J (Clin Res Ed) |volume=291 |issue=6509 |pages=1644 |date=December 1985 |pmid=2866807 |pmc=1418389 |doi= 10.1136/bmj.291.6509.1644-a|url=}} 2. ^{{cite journal | last1 = E.
