Reaction of 3-(pyridin-2-yl)-imidazo[1,5-a]pyridine (HPIP), CuCl₂·2H₂O and picolinaldehyde in the mixture of CH₃COOH and EtOH under solvothermal conditions gave complexes [LCuCl][Cu₂Cl₃] (1) and [HLCuCl]₂[CuCl₂]₂[CuCl₃]·2H₂O (2) (L=1,1'-(pyridin-2- ylmethylene)bis[3-(pyridin-2-yl)imidazo[1,5-a]pyridine]) simultaneously. The ligand L was generated via in situ metal-ligand reaction between HPIP and picolinaldehyde. When CuCl₂·2H₂O was replaced by CuCl, the 2:1:1 (HPIP:picolinaldehyde:CuCl) reaction afforded complex [Cu₃L₂Cl₂][CuCl₂]·2H₂O (3) and the analogous 2:1:3 reaction generated compound [Cu₃L₂][CuCl₂]₃ (4). Complexes 1 and 2 are Cu^II/Cu^I mixed-valence compounds. Complexes 1~4 display four various structures. It is found that the formation of the L ligand is controlled by CH₃COOH. This work reveals that the structures of complexes 1~4 could be rationally tuned via the inclusion of CH₃COOH in the reaction systems, the proper selection of different starting materials and the dexterous adjustment of the ratio of the starting materials.
