In–E–MI ternary clusters (E = S, Se; MI= Cu, Ag): Synthesis, structural characterization and optical band gap energy evaluation

Systematic Access of Ternary Organotetrel‐Copper Chalcogenide Clusters by [PhTE3]3− Anions (T=Si, Sn; E=S, Se)

“…Discrete complexes and clusters of such compositions have received a lot of attention in recent times owing to their potential as precursors to said materials, as showcased for CuInE 2 (E=S, Se), a promising semiconductor material for energy conversion in solar cells [3–7] . For this reason, many activities in this direction so far have addressed group 13 compounds, be it as supertetrahedral anions [8–12] or as neutral cages [13–17] . Krautscheid and co‐authors have published a series of investigations on compounds exhibiting organic substituents at the group 13 metal, such as [R 3 PCu) 4 (MeM) 4 E 6 ] (R=organic substituent; M=Ga, In) [18–21] .…”
