The Ag(I) coordination networks, {[Ag(1,4-dithiane)]BF4}( and {[Ag2(1,4-dithiane)3](BF4)2}( have been prepared and structurally characterised, establishing the role of this simple thioether molecular rod in the construction of coordination networks. In the structure of {[Ag(1,4-dithiane)]BF4}( linear one-dimensional chains are formed, the arrangement of which is controlled by weak Ag⋯F2BF2 interactions [F⋯Ag = 2.886(2)Å]. In {[Ag2(1,4-dithiane)3]BF4)2}( an unusual honeycomb network is observed.
