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)

Spectroscopic and structural characterizations of MX:dpem (1:1) ('dpem' = Ph2ECH2EPh2) are reported for MX = AgCl, Br; CuI, CN/Cl (all isomorphous) and AgI, AgSCN, CuSCN arrays, all being of the novel form [(μ-X){M(μ-X)(As-dpam-As′)2M′}]∞, essentially the familiar M(E-dpem-E′)2M′ binuclear array with both 'bridging' and (linking) 'terminal' (pseudo-)halides involved in the polymer.
