A series of reactions of different silver thiolates, AgSR (R = Mes (mesityl), Nph (naphthyl), Cy (cyclohexyl)), with bidentate phosphanes was performed yielding a bunch of new compounds, which were characterized by single crystal X-ray diffraction. Depending on the nature of the thiolate and the phosphane the solid state structure of the products varies from discrete complexes or clusters to a 3-dimensional coordination network. The mesityl group favors the formation of trinuclear units which are then linked in one, e.g. [Ag3(SMes)3(dpph)2] (5), two, e. g. [Ag 3(SMes)3 (dpppt)2] (4), or three dimensions [Ag3(SMes)3(dppb)2] (3), via the phosphanes. With naphthyl and cyclohexyl groups mostly clusters are formed which are either isolated with some phosphanes in their ligand sphere, e.g. [Ag 12(SCy)12(dpppt)2] (13), or additionally linked by the phosphanes to form 1-dimensional chains, e.g. [Ag12(SCy) 12(dppo)] (17).

Uptake of a Hg or Hg2 unit into the center of cage-type platinum clusters supported by diphosphines having long methylene carbon chains: X-ray structure of *2C6H6 (dpphex = 1,6-bis(diphenylphosphino)hexane, R = 2,6-dimethylphenyl)

When Pt(COD)Cl2 was treated with sodium amalgam in the presence of aromatic isocyanide (RNC, R = 2,6-Me2C6H3 (Xyl) or 2,4,6-Me3C6H2 (Mes)) and diphosphine with long methylene chain (diphos = Ph2P(CH2)nPPh2, n = 5 (dpppn) or 6 (dpphex)), two kinds of Hg-Pt mixed metal clusters, (2) and (3), were obtained.The structure of 3b (R = Xyl, diphos = dpphex) was determined by an X-ray analysis to be a cage-type cluster where a Hg2 unit was incorporated into a trigonal-anti-prismatic platinum core, two Pt3 triangles being supported by three dpphex ligands (close-type).The cluster 2 was assumed to have an incomplete cage-type structure (open-type), and was converted to close-type 3 by treatment with an equivalent diphosphine ligand.When dppb (n = 4) was used, an open-type mixed metal cluster in which one mercury atom was captured, (4), was obtained as the sole product.
