ABSTRACT
A tray-shaped Pd(II)3Au(I)3 complex (1) is prepared from 3,5-bis(3-pyridyl)pyrazole by means of tricyclization with Au(I) followed by Pd(II) clipping. Tray 1 is an efficient scaffold for the modular assembly of [3×n] Au(I) clusters. Treatment of 1 with the Au(I)3 tricyclic guest 2 in H2O/CH3CN (73) or H2O results in the selective formation of a [3×2] cluster (1â
2) or a [3×3] cluster (1â
2â
1), respectively. Upon subsequent addition of Ag(I) ions, these complexes are converted to an unprecedented Au3-Au3-Ag-Au3-Au3 metal ion cluster.
