Four new complexes [Cu(L 1 ) 2 ] n ( 1 ), [Mn(L 1 ) 2 ] n ( 2 ), [Cu(L 2 ) 2 ] n ( 3 ), [Mn(L 2 ) 2 ] n ( 4 , HL 1 = 2‐(((4H‐1,2,4‐triazol‐4‐yl)imino)methyl)‐4,6‐dichlorophenol; HL 2 = 2‐(((4H‐1,2,4‐triazol‐4‐yl)imino)methyl)‐4,6‐dibromophenol) were synthesized by microreaction bottle method. Complexes 1 and 3 and 2 and 4 are isomorphous heterostructures having the same molecular structure. The structures of 1 – 4 were characterized using single X‐ray diffraction, Fourier‐transform infrared spectroscopy, powder X‐ray diffraction, and thermogravimetric analysis, and their potential applications were analyzed by detecting their fluorescence and electrochemical luminescence (ECL). Hirshfeld surface analysis indicates that X···H (X = Br, Cl) interactions play a crucial role in stabilizing the self‐assembly process of 1 – 4 , which show highly intense ECL in N , N ‐dimethylformamide solution and high thermal stability.
