Replacement of the water by chloride ions. In the presence of chloride ions (for example with chromium(III) chloride), the most commonly observed colour is green. This happens when two of the water molecules are replaced by chloride ions to give the tetraaquadichlorochromium(III) ion - [Cr(H 2 O) 4 Cl 2] + [Co(NH 3) 6] 3+ is diamagnetic, with a low-spin octahedral Co(III) center. The cation obeys the 18-electron rule and is considered to be a classic example of an exchange inert metal complex. As a manifestation of its inertness, [Co(NH 3) 6]Cl 3 can be recrystallized unchanged from concentrated hydrochloric acid: the NH 3 is so tightly bound to the Co(III) centers that it does not dissociate to.

Chloropentammine Cobalt(III) Chloride In this lab, we will prepare the cobalt(III) complex chloropentammine cobalt(III) chloride. This requires a redox reaction since we begin with cobalt(II) that is oxidized via hydrogen peroxide to form the cobalt(III) specie. The final product is: Co H 3N H 3N NH 3 NH 3 Cl NH 3 2Cl (2+ English: Ultraviolet-visible spectroscopy of isomerisation kinetics from trans-Dichlorobis(ethylenediamine)cobalt(III) chloride to cis-Dichlorobis(ethylenediamine)cobalt(III) chloride in Methanol, T=50°C. The top (red) one is for cis- and the bottom (denser) ones are for trans- isomer. Measured at University of Graz Cobalt[II] chloride was tested in one study in rats by repeated subcutaneous injection, producing many local and a few distant subcutaneous sarcomas. Cobalt[II,III] oxide was tested in one experiment in hamsters to determine the effects of various particulates on carcinogenesis induced by N -nitrosodiethylamine
