Popis:	Two novel 3D coordination polymeric networks based on Ag(I) and TTF derivatives, [Ag4(tces-TTF)2(CF3SO3)2](CF3SO3)2 (tces = 2,3,6,7-tetra(cyanoethylsulfanyl)) (1) and [Ag2(bmdt)2](SbF6)2 · 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 65.8. The conductivity of complex 1 was measured at RT with a σ value of 3.47 × 10−6S cm−1 due to the S⋯S contacts in the molecules, while 2 is an insulator at RT.
