catena-Poly[silver(I)-bis­[μ-4-methyl-1H-1,2,4-triazole-3(4H)-thione-κ(2) S:S]-silver(I)-di-μ-thio­cyanato-κ(2) S:N;κ(2) N:S]

In the title one-dimensional coordination polymer, [Ag(2)(NCS)(2)(C(3)H(5)N(3)S)(2)](n), the Ag(I) atom adopts a distorted tetra­hedral AgNS(3) 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 thio­cyanate bridges linking through both S and N atoms (μ-1,3-SCN). An intra­chain N—H⋯N hydrogen bond occurs between the NH group of the triazole ring and the N atom of the thio­cyanate bridging ligand. A (101) sheet structure arises from inter­chain S⋯N short contacts [3.239 (3) Å] involving the thio­cyanate S atom and the triazole-ring N atom and possible very weak π–π stacking [centroid–centroid separation = 4.0762 (18) Å] between the triazole rings.
