Kupferchalkogenid-Clusterverbindungen mit Brom-funktionalisierter Ligandenhülle
Résumé
Five new copper chalcogenide cluster molecules, [Cu4(S-C6H4-Br)4(PPh3)4] (1), [Cu22Se6(S-C6H4-Br)10(PPh3)8] (2), [Cu28Se6(S-C6H4-Br)16(PPh3)8] (3), [Cu47Se10(S-C6H4-Br)21(OAc)6(PPh3)8] (4) and [Cu8(S-C6H4-Br)6(S2C-NMe2)2(PPh3)4] (5) have been synthesized and characterized by single crystal X-ray structure analysis. 1–4 were prepared from the reaction of CuOAc, Br-C6H4-SSiMe3 and Se(SiMe3)2 in the presence of PPh3. In a further reaction of 1 with iPrMgCl and (Me2N-CS2)2 cluster 5 was crystallized.
