Werner cobalt complexes

I have a 3-week lab experiment in my sophomore inorganic course that I call Project Werner, heavily adapted from Angelici's text, in which students first make their choice of 4 cobalt complexes: [Co(NH3)6]Cl3, [Co(NH3)5Cl]Cl2, [Co(NH3)4(CO3]NO3, or [Co(en)3]Cl3.  In the second week, everyone carries out ligand substitution of [Co(NH3)5Cl]Cl2 to prepare the two linkage isomers of [Co(NH3)5(NO2)]Cl
