Abstract Zero‐dimensional (0D) organic metal halides (OIMHs) with room‐temperature phosphorescent (RTP) properties have aroused great research enthusiasm due to their long lifetime of triplet excitons and environment stability. Despite extensive on the RTP emission OIMHs in different ions, there has been limited reporting excellent luminescent originating from ligands via metallic halide modulation, although they intriguing properties. Here, piperonylamine (piperA) is taken as cations two new are synthesized, 3 ClSbCl 5 ClInCl ·H 2 O, differently enhanced compared (piperA)Cl ligand. Structural photophysical studies reveal that increased π–π stackings between adjacent piperA O. Mechanism analysis demonstrates diverse stacking arrangements crystal structure result distinct energy transfer pathways, potentially accounting for varying degrees enhancement lifetime. This work developed a method regulating OIMH using ions achieve emission, providing approach designing ultra‐long materials.
