Organic–inorganic hybrid halides flourish due to their thermal stability, plasticity, and optical properties. However, performance optimization through reasonable regulation has always been a challenge. Diverse anions offer broad range of possibilities options for the development stimulus-responsive materials, thereby facilitating optimization. Here, we have successfully synthesized two organic–inorganic photoluminescent halides, (NNDP)2MnX4 (NNDP = N,N-dimethylpiperidinium chloride; X Cl, Br), with significant enhancement in photoluminescence quantum yield (4.38% → 39.91%) via halogen modulation. The increase is attributed distortion [MnX4]2– tetrahedron. Furthermore, phase-transition temperatures (NNDP)2MnCl4 (NNDP)2MnBr4 were determined as 347 335 K, respectively, thermodynamic measurement. Meanwhile, intermolecular forces analyzed using Hirshfeld surface two-dimensional (2D) fingerprint. This study injects new innovative ideas design novel materials.
