New oligo-/poly-meric forms for MX:dpex (1:1) complexes (M = CuI, AgI; X = (pseudo-)halide; dpex = Ph2E(CH2)xEPh2, E = (P), As; x = 1, 2)

Syntheses, spectroscopic (IR, NMR and ESI MS) and single crystal X-ray structural characterizations are reported for a wide variety of adducts of Ag(oxyanion):dpem(:S) (1:1(:n))2 (oxyanion = ClO4, F3CCO2 (tfa) F3CSO3 (tfs); dpem = Ph2E(CH2)EPh2) stoichiometry among which the basic Ag(Ph2E(CH2)EPh2)2Ag core is diversely perturbed by interactions with anions and solvent molecules. ESI MS and 31P NMR spectroscopy indicated that dinuclear species also exist in solution.
