Carbonatobis(ethylenediamine)cobalt(III) chloride is a salt with the formula [CoCO3(en)2]Cl (en = ethylenediamine). It is a red diamagnetic solid that is soluble in water. It is the monochloride salt of a cationic carbonate complex [CoCO3(en)2+. The chloride ion in this salt readily undergoes ion exchange. The compound is synthesized by the oxidation of a mixture of cobalt(II) chloride, lithium hydroxide, and ethylenediamine in the presence of carbon dioxide: [1]
The cationic complex is octahedral with C2 symmetry. [2]
The carbonato ligand is readily replaced upon acid hydrolysis. Derivatives include the following complexes: cis- and trans-[CoCl2(en)2+, cis-[Co(OH)(H2O)3(en)22+, cis-[Co(OH2)2(en)2+, and cis-[Co(NO2)2(en)2+. [1] Reaction with trifluoromethanesulfonic acid (HOTf) gives [Co(OTf)2(en)2]OTf. [3]
