摘要 Reaction of 3-（pyridin-2-yl）-imidazo[1,5-a]pyridine （HPIP）, CuCi2·2H20 and picolinaldehyde in the mixture of CHaCOOH and EtOH under solvothermal conditions gave complexes [LCuCI][CuECI3] （1） and [HLCuC1]E[CuCI2]2[CuCI3].2H20 （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 CuCI2·2H20 was replaced by CuC1, the 2：1：1（HPIP：picolinaldehyde：CuCI） reaction afforded complex [CuaL2CI2][CuCI2]·2H20 （3） and the analogous 2：1：3 reaction generated compound [CuaL2][CuCI2]3 （4）. Complexes 1 and 2 are Cun/CuI 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.
