20.500.12556/DiRROS-31163 Systematic investigation of coordination compounds in the CuCl–DABCO–HCl composition space diagram This study is devoted to the investigation of the copper (I) chloride–HCl − 1,4-diazabycyclo[2.2.2]octane composition diagram. Electrochemical and solvothermal syntheses were performed in this investigation. CuCl2, which is more soluble than CuCl, comproportionates with copper anode in the electrochemical technique and with copper powder in the solvothermal method, forming monovalent copper CuIin situ. HCl promotes the formation of different protonated forms of diamine by forming a specific pH of the reaction mixtures. The (HDABCO+)Cu2Cl3compound was synthesized in ethanol by electrochemical and solvothermal techniques. The Cu2Cl2(DABCO) compound was synthesized electrochemically in ethanol and in methanol. The compound [Cu4Cl6(DABCO)][Cu (H2O)4] was synthesized under solvothermal conditions in ethanol at 150 °C. Decreasing the temperature to 130 °C leads to the formation of compound Cu4Cl7(HDABCO+)3. Changing the solvent to methanol using the same amounts of reagents leads to the (HDABCO+)Cu5Cl6(DABCO) formation. CuCl reacts under solvothermal conditions with an ethanol solution of DABCO, forming Cu6Cl6(DABCO)2. Formed in situ by the decomposition of acetonitrile under hard solvothermal conditions (170 °C), CN groups play a key role in the formation of the compound (HDABCO+)CuCl(CN).
