trans-Dichlorobis(ethylenediamine)cobalt(3) chloride is a salt with the formula [CoCl2(en)ii]Cl (en = ethylenediamine). It is a green diamagnetic solid that is soluble in h2o. It is the monochloride salt of the cationic coordination complex [CoClii(en)2]+. One chloride ion in this salt readily undergoes ion exchange but the two other chlorides are less reactive, being spring to the metal center. The more stable trans-dichlorobis(ethylenediamine)cobalt(III) chloride is also known.
Synthesis [edit]
The compound is synthesized by the reaction of cobalt(II) chloride and ethylenediamine in muriatic acid in the presence of oxygen:
- 4 CoCl2 + eight en + 4 HCl + Otwo → 4 trans-[CoCltwo(en)2]Cl + 2 HiiO
The initial production contains HCl, which is removed past heating. Alternatively, (carbonato)bis(ethylenediamine)cobalt(III) chloride reacts with muriatic acid at 10 °C to give the same species.[1]
- [Co(CO3)(en)2]Cl + two HCl → trans-[CoCl2(en)2]Cl + COtwo + H2O
UV-vis spectra of diverse stages in the conversion of trans-[CoCl2(en)2]+ to the cis isomer.
Comparison of cis and trans isomers [edit]
This common salt is more soluble than the cis isomer. This pair of isomers was pregnant in the evolution of the surface area of coordination chemistry.[2]
The trans isomer cation has idealized D2h point group symmetry, whereas the cis isomer cation has C2 symmetry.
