AbstractReaction of 3-(pyridin-2-y1)-imidazo[1,5-a]pyridine (HPIP), CuCl2.2H(2)O and picolinaldehyde in the mixture of CH3COOH and EtOH under solvothermal conditions gave complexes [LCuCl][Cu2Cl3] (1) and [HLCuCl](2)[CuCl2](2)[CuCl3].2H(2)O (2) = 1X-(pyridin-2-yl-methylene)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 CuCl2.2H(2)O was replaced by CuCl, the 2:1:1 (HPIP:picolinaldehyde:CuCl) reaction afforded complex [Cu3L2Cl2][CuCl2].2H(2)O (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 similar to 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 similar to 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.
