WebSep 25, 2002 · A nanosized decacopper(II) cluster complex was synthesized using p-tert-butylthiacalix[6]arene as a ligand. In the complex, the calixarene assumes a "pinched cone" conformation and acts as an undecadentate ligand via six phenoxy oxygen and five sulfur atoms. The resulting pentacopper(II) subunits are connected by two hydroxo and … WebHere, we report the largest known mixed-valence silver nanocluster [Ag 155 (CyS) 40 (TC4A) 5 Cl 2] (Ag155) protected by deprotonated cyclohexanethiol (CySH) and macrocyclic ligand p-tert-butylthiacalix[4]arene (H 4 TC4A).
