Four new copper(II) complexes [Cu(HL)(im)](ClO4)2 (1), [Cu(HL)(py)](ClO4)2 (2), [Cu2(HL)2(bpy)2](ClO4)4·H2O (3), and [Cu2(HL)2(bpy)](ClO4)4·H2O (4) (im = imidazole; py = pyridine; bpy = 4,4′‐bipyridine) were synthesized by reactions of tripodal ligandN1‐(2‐aminoethyl)‐N1‐(1H‐imidazol‐4‐ylmethyl)‐ethane‐1,2‐diamine(HL) and Cu(ClO4)2·6H2O with different nitrogen‐containing aromatic ligands. It was found that the size of the N‐containing aromatic ligand, and the ratio of the ligand and metal ion, have great influence on the formation and structure of the complexes.
