Single-crystal X-ray structural characterizations of MX:dpam (1:1) ('dpam' = Ph2AsCH2AsPh2) 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. A different arrangement of bridging and linking entities is found with AgX:dpae (1:1) 2(∞|∞), X = Br, NCO, 'dpae' = Ph2As(CH 2)2AsPh2, now comprising [M(μ-X) 2(As-dpae-As)M] kernels linked by As-dpae-As′, while in the thiocyanate analogue Ag(NCSSCN)Ag units are linked by the dpae ligands into a two-dimensional web. Synthetic procedures for all adducts have been reported. All compounds have been characterized both in solution (1H, 13C, 31P NMR, ESI MS) and in the solid state (IR). © 2004 Elsevier B.V.
