Synthesis of [Co NH3 6]Cl3:1. Start with an aqueous solution of a cobalt III salt, such as cobalt III chloride hexahydrate CoCl36H2O .2. Add an excess of concentrated ammonia solution NH3 to the cobalt III salt solution. The ammonia will act as a ligand and form a complex with the cobalt III ion.3. Stir the mixture and heat it gently to promote the formation of the complex. The solution will change color as the complex forms.4. After the reaction is complete, cool the solution and filter off any unreacted cobalt III salt or other impurities.5. Evaporate the filtrate to obtain crystals of the coordination compound [Co NH3 6]Cl3.Characterization using UV-Vis and IR spectroscopy:1. UV-Vis spectroscopy: Dissolve a small amount of the synthesized [Co NH3 6]Cl3 in an appropriate solvent, such as water or a mixture of water and ethanol. Measure the UV-Vis spectrum of the solution using a UV-Vis spectrophotometer. The spectrum will show absorption bands corresponding to the d-d transitions of the cobalt III ion in the complex. The position and intensity of these bands can be used to confirm the formation of the complex and provide information about its electronic structure.2. IR spectroscopy: Prepare a KBr pellet containing a small amount of the synthesized [Co NH3 6]Cl3. Measure the IR spectrum of the pellet using an IR spectrometer. The spectrum will show characteristic bands corresponding to the stretching and bending vibrations of the NH3 ligands in the complex. These bands can be used to confirm the presence of ammonia ligands in the complex and provide information about their bonding to the cobalt III ion.By comparing the obtained UV-Vis and IR spectra with the literature data, you can confirm the successful synthesis and characterize the coordination compound [Co NH3 6]Cl3.
