Abstract:Two novel 3D coordination polymeric networks based on Ag(I) and TTF derivatives, [Ag-4(tces-TTF)(2)(CF3SO3)(2)](CF3SO3)(2) (tces = 2,3,6,7-tetra(cyanoethylsulfanyl)) (1) and [Ag-2(bmdt)(2)](SbF6)(2) center dot acetone (bmdt = 4,5-bis(methylsulfanyl)-1,3-dithiole-2-thione) (2), were synthesized and crystallographically characterized. Both 1 and 2 have axially chiral helical motifs and these helices were assembled in a similar way: spiral up along b axis infinitely. In addition, complex 2 forms a "cds" network with a topology of 6(5).8. The conductivity of complex 1 was measured at RT with a a value of 3.47 x 10(-6)S cm(-1) due to the S center dot center dot center dot S contacts in the molecules, while 2 is an insulator at RT.
