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-H⋯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 S⋯N short contacts [3.239 (3) Å] involving the thio-cyanate 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.
在一维配位聚合物[Ag2(NCS)2(C3H5N3S)2]n中，Ag(I)原子采用扭曲的四面体AgNS3几何构型。[001]链中相邻的Ag(I)原子通过成对的桥连4-甲基-1H-1,2,4-三唑-3(4H)-硫酮（Hmptrz）配体（通过其S原子）和通过S和N原子连接的双硫氰酸酯桥（μ-1,3-SCN）交替相连。在三唑环的NH基团与硫氰酸酯桥连配体的N原子之间形成链内N-H⋯N氢键。(101)层状结构由涉及硫氰酸酯S原子和三唑环N原子的链间S⋯N短接触[3.239 (3) Å]以及三唑环之间可能非常弱的π-π堆积[质心-质心间距 = 4.0762 (18) Å]产生。
