Synthesen und Molekülstrukturen von [Cu20Ga10Cl4Se23(PEt2Ph)12] und [Cu14In6Se7(iPrSe)18]

Syntheses and Structures of Cu₂₀Ga₁₀Cl₄Se₂₃(PEt₂Ph)₁₂] and Cu₁₄In₆Se₇(iPrSe)₁₈] CuCl and GaCl₃ react with Se(SiMe₃)₂ in thf solution to yield in the presence of PEt₂Ph Cu₂₀Ga₁₀Cl₄Se₂₃(PEt₂Ph)₁₂] ( 1 ). Reaction of CuCl, InCl₃ and TMEDA with iPrSeSiMe₃ in DME results in the crystallisation of Cu₁₄In₆Se₇(iPrSe)₁₈] ( 2 ). The structures of 1 and 2 were determined by X‐ray single crystal structure analysis and display two new types of molecular clusters formed by the elements of group 11, 13, and 16. However, both cluster structures show no analogy to the structures of the related bulk phases.
