ABSTRACT
In the title one-dimensional coordination polymer, [Ag2(NCS)2(C3H5N3S)2] n , the Ag(I) atom adopts a distorted tetra-hedral AgNS3 geometry. Adjacent Ag(I) atoms in the [001] chain are alternately linked by pairs of bridging 4-methyl-1H-1,2,4-triazole-3(4H)-thione (Hmptrz) ligands (via their S atoms) and double thio-cyanate bridges linking through both S and N atoms (µ-1,3-SCN). An intra-chain N-Hâ¯N hydrogen bond occurs between the NH group of the triazole ring and the N atom of the thio-cyanate bridging ligand. A (101) sheet structure arises from inter-chain Sâ¯N short contacts [3.239â (3)â Å] involving the thio-cyanate S atom and the triazole-ring N atom and possible very weak π-π stacking [centroid-centroid separation = 4.0762â (18)â Å] between the triazole rings.
