The title compound, [Ag(C3H5OS2)]n, is polymeric in the solid state and adopts a layered structure in which each Ag atom is five-coordinated in a distorted trigonal-bipyramidal geometry defined by four S atoms belonging to four different xanthate groups and by a neigbouring Ag atom [Ag...Ag = 3.0540 (8) A]. Each S atom is three-coordinated to one C and two Ag atoms. The structure can be envisaged as being formed by Ag2(S2COEt)2 units in which every S atom is bonded to another Ag atom from a different unit and the Ag atoms are also bonded to two different S atoms of two other units. The result is a two-dimensional network of condensed metallacycles of six or eight atoms.

A series of highly phosphorescent PtAg2 heterotrinuclear alkynyl complexes with bis(diphenylphosphinomethyl)phenylphosphine (dpmp) were prepared and characterized structurally. The solution phosphorescence with various emitting colors is systematically modulated by modifying substituents as well as π-conjugated systems in aromatic acetylides. The crystals, powders, or films exhibit reversible stimuli-responsive phosphorescence changes upon exposure to vapor of MeCN, pyridine, DMF, etc., resulting from perturbation of d 8-d10 metallophilic interaction in the excited states as a consequence of the formation/disruption of Ag-solvent bonds. Both experimental and time-dependent density functional theory (TD-DFT) studies demonstrate that d8-d10 metallophilic interaction exerts a crucial role on phosphorescent characteristics due to the PtAg2 cluster-based 3[d → p] state. This study affords a paradigm for phosphorescence modulation in d8-d10 heteronuclear complexes.

From the interaction between imidazole-type ligands B and [Ag(PPh3)4]X (X = NO3, BF4, ClO4 or CF3CO2), [Ag(PCy3)2(NO3)] and [Ag(PPh3)X)] (X = NO2 or CH3SO3), new ionic mononuclear [Ag(PR3)4-n(B)n]+[X]- (R = Ph or Cy) and neutral mono- ([Ag(PR3)3-n(B)n(X)]) and di-nuclear ([{Ag(PPh3)(B)(μ-X)}2]) complexes have been obtained which have been characterized through elemental analysis, IR and far-IR, conductivity, 1H NMR and in some cases also by vaporimetric molecular weight measurements and 31P NMR. Stoichiometries and molecular structures are dependent on the nature of the azole (steric hindrance and basicity), of the counter ion, and on the number of the P-donor ligands in the starting reactants. Solution data are consistent with a partial dissociation of complexes, occurring through breaking of both Ag-N and Ag-P bonds. The majority of the possible Ph3P/imidazole base combinations have been characterized structurally by room-temperature single crystal X-ray studies, thus: [Ag(PPh3)3(4-Ph-im)]NO3 (4-Ph-im = 4-phenylimidazole), [Ag(PPh3)2B2]NO3 for B = imidazole (Him) or 2-methylimidazole (2-Me-im), [Ag(PPh3)(2-Me-im)3][CF3CO2], [Ag(PPh3)2(2-Me-im)(O2NO)], [{Ag(PPh3)(1-Me-im)(μ-OSOCH3O)}2] and [{Ag(PPh3)(Him)(μ-ONO)}2]; the latter is a mixture of isomers in which one or both oxygen atoms of the anions interact with silver atoms. In the methanesulfonate complex the interactions of the anions with the silver may be regarded as a perturbation on a proto-linear P-Ag-N array (Ag-P,N 2.3662(6), 2.189(1) A P-Ag-N 144.28(6)°).

The silver(I) isocyanide complexes ClO4 (R = Me, cyclo-C6H11, or But) and ClO4 have been prepared, their i.r., Raman, 1H and 13C n.m.r. spectra recorded, and assignments proposed.Particular emphasis has been placed on an assigment of the vibrational spectrum of ClO4.Some reactions of ClO4 and t)4>ClO4 with neutral Group 5 donor ligands have been examined.Complete isocyanide displacement leads to the complexes ClO4 .The mixed-ligand complexes ClO4 (R = C6H11 or But; bipy = 2,2'-bipyridyl), ClO4 (py = pyridine) and ClO4 L3 = (Ph2PCH2)3CMe, L = P(OMe)3> have also been prepared.The complexes involving nitrogen donors appear to contain three-co-ordinate silver(I) whereas those involving phosphorus donors contain four-co-ordinate silver(I).
