Procedure for the synthesis of a coordination compound:1. Preparation of the reagents:a. Ethylenediamine en : Ensure that the ethylenediamine is of high purity and is stored in a sealed container to prevent evaporation and contamination.b. Copper II chloride CuCl2 : Prepare a 0.1 M solution of copper II chloride in distilled water. Make sure to use high purity CuCl2 and distilled water to avoid any impurities.2. Synthesis of the coordination compound:a. In a 250 mL round-bottom flask, add 50 mL of the 0.1 M CuCl2 solution.b. Slowly add 50 mL of ethylenediamine to the CuCl2 solution with constant stirring. The solution should turn blue-green, indicating the formation of the coordination compound.c. Continue stirring the mixture for 30 minutes to ensure complete complexation.d. Remove the solvent by rotary evaporation or by heating the solution gently under reduced pressure. The resulting solid should be the desired coordination compound.3. Characterization of the synthesized compound:a. Melting point: Determine the melting point of the synthesized compound using a melting point apparatus. Record the temperature range at which the compound melts.b. Infrared spectra: Obtain the infrared IR spectrum of the synthesized compound using an IR spectrometer. Analyze the spectrum for characteristic peaks that indicate the presence of specific functional groups or bonds.c. Magnetic susceptibility: Measure the magnetic susceptibility of the synthesized compound using a magnetic susceptibility balance or a SQUID magnetometer. This will provide information about the magnetic properties of the compound and help determine its structure.4. Discussion of the possible structures of the formed compound:Based on the obtained results, we can discuss the possible structures of the synthesized coordination compound. For example:a. If the melting point is significantly different from that of the starting materials, it suggests the formation of a new compound.b. The IR spectrum can provide information about the coordination environment of the copper II ion. For instance, the presence of a strong peak around 1600 cm-1 may indicate the coordination of the ethylenediamine nitrogen atoms to the copper II ion.c. The magnetic susceptibility data can help determine the geometry of the complex. A high magnetic susceptibility value may suggest an octahedral geometry, while a low value may indicate a square planar geometry.Based on the combination of these results, we can propose a possible structure for the synthesized coordination compound. For example, if the IR spectrum shows peaks consistent with ethylenediamine coordination and the magnetic susceptibility data suggest an octahedral geometry, the compound could be [Cu en 2Cl2], where the ethylenediamine ligands are coordinated to the copper II ion in a bidentate manner, and the chloride ions complete the octahedral coordination sphere.
