%X The organoplatinum complex of a primary amine and AgClO<sub>4</sub> aggregate in methanol to oligonuclear mixed-metal species. A perchlorate salt 3 with the empirical formula C<sub>96</sub>H<sub>146</sub>Ag<sub>7</sub>Cl<sub>13</sub>N<sub>12</sub>O<sub>62</sub>Pt<sub>6</sub> could be isolated and structurally characterized with the help of X-ray diffraction at the DESY synchrotron. The product contains both a penta- and a tetra-nuclear complex cation in which Ag(I) and Pt(II) alternate, held together without any conventional bridge. The cationic species feature short Ag⋅⋅⋅Pt distances between 2.7 and 2.9 Å and contacts longer than 2.4 Å between Ag and C atoms in aromatic rings. In addition to the interactions with Ag(I) cations, Pt(II) is in a square-planar arrangement, coordinated by a chelating and a terminal amine and an aqua ligand. The central Ag(I) in the pentanuclear cation is located on a twofold crystallographic axis and not involved in any obvious coordinative bond; it exclusively shows short contacts to the neighboring Pt(II) ions and the Pt-bonded, formally anionic carbon atoms of the cyclometallated organic ligand. Powder diffraction shows that 3 melts and re-solidifies without decomposition.
