Poly[[{μ(4)-2,2'-[butane-1,4-diylbis(sulfanedi-yl)]bis-(1,3,4-thia-diazole)}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 thia-diazole rings of three symmetry-related 2,2'-[butane-1,4-diylbis(sulfanedi-yl)]bis-(1,3,4-thia-diazole) 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 thia-diazole ligands into a layer network extending parallel to (0-21). The crystal structure is stabilized by inter-molecular O-H⋯O hydrogen bonds. The O atoms of the perchlorate anion and one water mol-ecule 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.
