A facile route was demonstrated for inorganic SnX‐complex‐induced syntheses of self‐assembled 1D columnar, 2D raftlike, and 3D stratiform anisotropic Cu 2 S hexagonal nanoplates. The factors (reaction time, temperature, the concentration of SnX complex, and so on) that influence the size, phase, monodispersity, and self‐assembly ability of the Cu 2 S hexagonal nanoplates were studied in detail. It was found that the SnX complex could inhibit the growth of the <001> direction of monoclinic Cu 2 S nanocrystals, which further induced the formation of the hexagonal lamellar structure. Furthermore, it revealed that the formation of the 1D arrangement was preferred as particles stacked in a face‐to‐face configuration by maximizing ligand–surface interactions. Then, high ligand density along the side of the 1D columnar arrangement induced well‐defined 2D raftlike and 3D stratiform self‐assembly.
