Poly[[{μ4-2,2′-[butane-1,4-diylbis(sulfanediyl)]bis(1,3,4-thiadiazole)}silver(I)] perchlorate sesquihydrate]

Abstract

In the polymeric title compound, {[Ag(C8H10N4S4)]ClO4·1.5H2O}n, the AgI 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 AgI 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.
