(a) Synthesis of [Pd13(μ4-PCP)6(μ-Cl)3][B(ArF)4]2 (2) and [Pd17(μ3-PCP)8(μ4-Cl)2][B(ArF)4]3 (3). (b) Ball-and-stick representation of the X-ray structure of 2, a drawing of the anticuboctahedral Pd13 core of 2, and a drawing highlighting the μ4-coordination mode of the PCP ligands in 2. (c) Ball-and-stick representation of the X-ray structure of 3, a drawing of the square gyrobicupola Pd17 core of 3, and a drawing highlighting the μ3-coordination mode of the PCP ligands in 3. For (b) and (c), orange = Pd; green = Cl; dark gray = C; the counteranions and solvent molecules were omitted for clarity.
