چکیده
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.

In the title coordination polymer, [CuBr(C(3)H(5)N(3)S)](n), the Cu(I) atom adopts a tetra-hdral CuS(2)Br(2) coordination geometry arising from two S-bonded 4-methyl-1H-1,2,4-triazole-3(4H)-thione ligands and two bromide ions. Both the S and Br atoms act as bridging ligands, connecting pairs of Cu(I) atoms and generating chains propagating in [100]. Inter-chain N-H⋯N hydrogen bonds generate lay...
