Poly[[{μ(4)-2,2′-[butane-1,4-diylbis(sulfanedi­yl)]bis­(1,3,4-thia­diazole)}silver(I)] perchlorate sesquihydrate]

In the polymeric title compound, {[Ag(C(8)H(10)N(4)S(4))]ClO(4)·1.5H(2)O}(n), the Ag(I) atom has a slightly distorted trigonal-planar coordination geometry provided by three N-atom donors from the thia­diazole rings of three symmetry-related 2,2′-[butane-1,4-diylbis(sulfanedi­yl)]bis­(1,3,4-thia­diazole) ligands. Centrosymmetrically related Ag(I) atoms are bridged by the N–N fragments of rings, forming six-membered dinuclear metallacycles, which are further linked by the alkyl spacers of the thia­diazole ligands into a layer network extending parallel to (0-21). The crystal structure is stabilized by inter­molecular O—H⋯O hydrogen bonds. The O atoms of the perchlorate anion and one water mol­ecule are disordered over two sets of sites with refined occupancy ratios of 0.640 (6):0.360 (6) and 0.663 (11):0.337 (11), respectively. The second water molecule shows half-occupancy.
