Synthesis and Crystal Structure of 1D Chainlike Ag(I) Complex Assembled by Biphenyl-2,2′,4,4′-tetracarboxylic Acid and 4,4′-Bipyridine

A novel Ag(I) complex based on 4,4'-bipyridine (4,4'-bpy) and biphenyl-2,2',4,4'-tetracarboxylic acid (H(4)btc), namely, {[Ag(4,4'-bpy)][Ag-2(H(3)btc)(H(2)btc)(4,4'-bpy)(2)]center dot 3H(2)O}(n) (1) has been hydrothermally synthesized and characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction analysis. The complex crystallizes in triclinic system, space group P (1) over bar with a=1.12251(6) nm, b = 1.55401(8) nm, c=1.774 59(9) nm, beta=91.641 0(10)degrees, V=2.8308(3) nm(3), Z=2, D-c=1.764 g.cm(-3), mu=1.113 mm(-1), F(000)=1 508, and the final R-1=0.045 0, wR(2)=0.086 2 for I>2 sigma (I). In complex 1, 1D linear [Ag(4,4'-bpy)](+) chains reside in 3D supramolecular structure of 1D{[Ag-2(H(3)btc)(H(2)btc)(4,4'-bpy)(2)](-) double-chains and dissociative water molecules assembled into by hydrogen bonds. In additional, thermal stability and electrochemistry of 1 have also been studied. CCDC: 840549.
