Such compounds would be of great interest if their optical and electronic properties could be rationally designed. Herein, we report a new example of metal halide cluster-assembled compound (C<sub>9<\/sub>NH<sub>20<\/sub>)<sub>9<\/sub>[Pb<sub>3<\/sub>Br<sub>11<\/sub>](MnBr<sub>4<\/sub>)<sub>2<\/sub>, featuring distinctly different anionic polyhedra, namely, a rare lead halide cluster [Pb<sub>3<\/sub>Br<sub>11<\/sub>]<sup>5\u2212<\/sup>&nbsp;and [MnBr<sub>4<\/sub>]<sup>2\u2212<\/sup>. In accordance with its multinary zero-dimensional (0D) structure, this compound is found to contain two distinct emission centers, 565\u2005nm and 528\u2005nm, resulting from the formation of self-trapped excitons and&nbsp;<sup>4<\/sup>T<sub>1<\/sub>&#8211;<sup>6<\/sup>A<sub>1<\/sub>&nbsp;transition of Mn<sup>2+<\/sup>&nbsp;ions, respectively.
