Synthesis, Structure, and Tunability of Zero-Dimensional Organic-Inorganic Metal Halides Utilizing the m-Xylylenediammonium Cation: MXD₂PbI₆, MXDBiI₅, and MXD₃Bi₂Br₁₂·2H₂O.

ABSTRACT: Over the past decade, the efficiency of photovoltaic devices based on CH₃NH₃PbI₃ have dramatically increased. This has driven research efforts in all areas, from the discovery of materials to film processing to long-term device stability studies. Here, we report the synthesis and structure of three new "zero dimensional" organic-inorganic metal halides which use the meta-xylylenediammonium (MXD) cation: MXD₂PbI₆, MXDBiI₅, and (MXD)₃Bi₂Br₁₂·2H₂O. The different structures of the new materials lead to compounds with a range of band gaps with MXDBiI₅ having the lowest at 2.15 eV. We have explored the tunabilty of MXDBiI₅ through halide substitution by preparing a
