Two novel copper β-diketonato complexes with halogen atoms are synthesized. The length of complex arms is slightly different. Scanning tunneling microscopy shows that the two complexes self-assemble into porous two-dimensional (2D) nanoarchitectures at the solid−liquid interface on graphite. These arrangements are however stabilized by the formation of two different halogen synthons between neighboring molecules. These synthons are composed of four or two type-II halogen bonds. These observations reveal that a tiny modification of complex design can drastically affect the structure of 2D halogen-bonded nanoarchitectures.
