The synthesis is relatively easy, but the procedure also involves some very interesting science.
There is a............ tutorial.

The orange brown crystals of Co(NH3)6Cl3
shown above were grown slowly over a period of several days. This slow
crystal growth created the large crystals.
|Cobalt is a
transition metal and as such its d orbitals are "being filled". They are part of
the valence shell and are used in bonding.
In Co(NH3)6Cl3, the six empty hybrid d2sp3 orbitals are used to bond with the nonbonding electron pair on ammonia.
|The Co(NH3)6+3 ion is octahedrally surrounded by the six ammonia molecules and gives rise
to a compact, relatively spherical ion.
SO in solution, where is the Cl of Co(NH3)6Cl3?
