abstract = {The organoplatinum complex of a primary amine and AgClO$_4$
aggregate in methanol to oligonuclear mixed-metal species. A
perchlorate salt 3 with the empirical formula
C$_{96}$H$_{146}$Ag$_7$Cl$_{13}$N$_{12}$O$_{62}$Pt$_6$ 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.},
