    • Recent X-ray crystallographic studies20 revealed that the Au12Ag7 and Au17Ag2 skeletons in Au12Ag7(PMe2Ph)10(NO 3)9 (1) and Au17Ag2(PMe 2Ph)10(NO3)9 (2, respectively, both form a 19-atom interpenetrating bi-icosahedral polyhedron (2 II; 1 DI) of D5h symmetry. Their ordered bimetallic cores consist of two outer eclipsed Ag-capped Au5 pentagons that each form Au-centered icosahedral cages with a staggered inner Ag5 pentagon in 1 that is replaced by a Au5 pentagon in 2

    • Based upon only crystallographic examples of the 26- and 29-atom II Pd kernels previously uncovered in the crystal structure determinations5 of 2 and 3, respectively, the same sequential II growth pathway and subsequent postulation concerning Pd-Pd bonding in these ligated palladium clusters being attributed primarily to attractive dispersion forces were initially postulated5 in 2001. The isolation, structural analysis, and resulting implications of the 23-atom II kernel in 1 (reported herein) furnish additional self-consistent strong support in favor of these experimentally based proposals, which indicate that palladium is the only known Group 8-10 transition metal that can simulate argon atoms in forming analogous icosahedral-based clusters
