Synthesis of [Co NH3 6]Cl3:1. Start with anhydrous cobalt III chloride CoCl3 as the metal precursor. You can obtain anhydrous CoCl3 by heating hydrated cobalt III chloride CoCl36H2O to remove the water molecules.2. Dissolve the anhydrous CoCl3 in a minimum amount of distilled water.3. Add concentrated ammonia solution NH3 dropwise to the CoCl3 solution. The solution will change color from brownish-red to dark brown and finally to a deep purple color, indicating the formation of the hexaamminecobalt III complex.4. Continue adding ammonia until the solution becomes clear and no more precipitate forms.5. Evaporate the solution to obtain purple crystals of [Co NH3 6]Cl3.Characterization of [Co NH3 6]Cl3 using analytical techniques:1. UV-Vis spectroscopy: Dissolve a small amount of [Co NH3 6]Cl3 in distilled water and measure its UV-Vis spectrum. The compound should exhibit a characteristic absorption band in the visible region due to the d-d transition of the Co III ion. The exact position of the absorption band will depend on the ligand field strength and the geometry of the complex.2. IR spectroscopy: Prepare a KBr pellet containing a small amount of [Co NH3 6]Cl3 and record its IR spectrum. The spectrum should show characteristic bands corresponding to the N-H stretching and bending vibrations of the ammonia ligands. Additionally, the absence of any bands related to water molecules will confirm the anhydrous nature of the compound.3. NMR spectroscopy: Since [Co NH3 6]Cl3 is a paramagnetic complex, it is not suitable for conventional 1H or 13C NMR spectroscopy due to the broadening of signals caused by the unpaired electrons in the Co III ion. However, you can use 14N NMR spectroscopy to study the ammonia ligands in the complex. Dissolve a small amount of [Co NH3 6]Cl3 in D2O and record the 14N NMR spectrum. The spectrum should show a single resonance corresponding to the coordinated ammonia ligands.4. Elemental analysis: Perform a quantitative elemental analysis of the synthesized [Co NH3 6]Cl3 to determine the percentages of Co, N, and Cl in the compound. The obtained values should be consistent with the theoretical values based on the molecular formula.5. X-ray crystallography: If single crystals of [Co NH3 6]Cl3 can be obtained, X-ray crystallography can be used to determine the exact structure and geometry of the complex, confirming the coordination number and the arrangement of the ammonia ligands around the Co III ion.
