Manganese-based hybrid metal halides are attractive for scintillator applications due to their high emission efficiency and good stability. However, most high-performance manganese scintillators rely on bulky and complex organic cations as A-site components, which reduce the lattice density and compromise X-ray absorption. To address this issue, we employed a small piperidinium cation (C<sub>5</sub>H<sub>12</sub>N<sup>+</sup>) to synthesize a zero-dimensional manganese halide, (C<sub>5</sub>H<su
