Luteocobalt chloride

Luteocobaltic chloride (modern, [Co(NH3)6]C13, hexaamminecobalt(III) chloride) is a stable yellow-orange compound.55 In solution, all the chlorine is immediately precipitated by silver nitrate. Treatment with hydrochloric acid at 100 °C does not remove any ammonia. Treatment with sulfuric acid does not remove any ammonia, but yields the compound Co2(S04)3T2NH3, i.e. the chlorine atoms are replaced by sulfate groups. Clearly, some sort of very stable metal—ammonia bonding but much less stable metal—chlorine bonding is indicated.

This is shown in the following Table 2, in which fourteen colloids are listed in the order of decreasing reciprocal hexol number. The table contains information on the flocculability with six different salts, viz., hexol nitrate (6—1) rhodochromium chloride (5—1) platinium triethylenediamine tetranitrate (4—1) luteocobalt chloride (3—1) CaCl2(2—1) and NaCl(l—1).
