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)

摘要: Single-crystal X-ray structural characterizations of MX:dpam (1:1) (‘dpam’ = Ph 2 AsCH AsPh ) are reported for MX = AgCl, Br; CuI, CN/Cl (all isomorphous) and AgI, AgSCN, CuSCN arrays, all being the novel form [(μ-X){M(μ-X)( As -dpam- ′) M′}] ∞ , essentially familiar M(E-dpem-E′) M′ binuclear array with both ‘bridging’ (linking) ‘terminal’ (pseudo-)halides involved in polymer. A different arrangement bridging linking entities is found AgX:dpae 2(∞|∞) X = Br, NCO, ‘dpae’ = Ph As(CH now comprising [M(μ-X) ( -dpae- )M] kernels linked by ′, while thiocyanate analogue Ag NCS SCN units dpae ligands into a two-dimensional web. Synthetic procedures adducts have been reported. All compounds characterized solution 1 H, 13 C, 31 P NMR, ESI MS) solid state (IR).
