In the title one-dimensional coordination polymer, [Ag2(NCS)2(C3H5N3S)2]n, the AgI atom adopts a distorted tetra­hedral AgNS3 geometry. Adjacent AgI 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 ππ stacking [centroid–centroid separation = 4.0762 (18) Å] between the triazole rings.

Comment top

One of the active areas of meterial research is the coordination compounds of the metal ions with the multifunctional ligands leading to the structural diversities and properties (Zhang et al., 2009; Wang et al., 2011). For this work, we report the mixed ligands Ag(I) complex containg multidonor atoms, 4-methyl-1,2,4-triazole-3-thiol (Hmptrz) and thiocyanate ligands. The Hmptrz is one of 1,2,4-triazole derivative ligands - based heterocyclic thioamide containing thiol group which has three potential donor atoms. Both Hmptrz and thiocyanate group are amphidentate ligands, which can bind to the metal center with either the N or S atom or both of them (Zhang et al., 1999; Jiang et al., 2011).

The title complex exhibits a one-dimensional chain polymeric structure and the asymmetric unit consists of one Ag(I) atom, one Hmptrz molecule and one SCN- anion. The chemical structure of this complex is shown in Scheme I and the crystal structure is depicted in Figure 1.

The Ag atom features a distorted tetrahedral environment with the range of angles from 101.00 (2) to 124.52 (3)o. Each Ag is bonded by two µ2-S-bridging atoms of two Hmptrz molecules with the distances of 2.5554 (8) and 2.6688 (8) Å. The other two coordination sites are occupied by S and N atoms from the different µ2-1,3-SCN bridges coordinated as a pair alternating bidentate end to end fashion similar to those complexes of the same thiocyanate bridges (Chen et al., 1999; Diaz et al., 1999; Goher et al., 2000; Song et al., 2000; Cai et al., 2007; Saithong et al. 2007). The Cu—Sthiocyanato and Cu—Nthiocyanato bond distances are 2.4987 (8) and 2.2354 (4) Å, respectively. The SCN bond angle is almost perfectly linear [178.6 (3)°] as compare with the same µ2-1,3-SCN configuration mode of those complexes (Vicente et al.,1997; Song et al., 2000). The S2—C4 and C4—N4 distances [1.646 (3) and 1.150 (4) Å] refer to thiocyanate resonance form which indicate to a π-delocalized system along the metal-thiocyanate chain (Zhang et al., 1999).

An infintite one-dimensional structure of this complex is based on [Ag(µ2-Hmptrz)(µ2-1,3-SCN)] double-bridges, in which both Hmptrz and SCN- ligands adopt the µ2-end-on and µ2-end-to-end bridging mode, respectively. As illustated in Figure 2, the Hmptrz and thiocyanato ligands interconnect the Ag(I) ions into an infinite chain generated by the unit c translation runing parallel to c axis, which consist of four-membered ring [—Ag—S—Ag—S—] and eight-membered ring [—Ag—SCN—Ag—SCN—]. In addition, The Ag···Ag separation with the distances of 3.3241 (5) Å in the four-membered ring is slighty shorter than the sum of the van der Waals radii of Ag atoms (3.44 Å), which indicates that there is the Ag···Ag interaction.

The weak intra-molecular hydrogen bonding interaction [N1—H1···N4i, (i) = -x + 1, -y, -z + 1] is found between N(1) of triazole ring and N(4) of thiocyanate bridging ligand at 2.954 (4) Å. The inter-short contact at 3.239 (3) Å arises from S2 donor of triazole ring with N2 acceptor from the thiocyanate bridge of the neighbouring adjacent chain which is smaller than the sum of S and N van der Waals radii (1.80 + 1.55 Å). In addition, the π···π stacking between the triazole rings of the neighbouring chain is observed with the centroid-centriod distance of 4.0762 (18) Å. Both of these interactions generate the supramolecular layer interactions related by ac-plane. A view of intra-molecular hydrogen bonding is depected in Figure 3 and The layered network interactions in crystal packing are shown in Figure 4.

Experimental top

A mixture of AgNO3 (0.15 g, 0.88 mmol), KSCN (0.09 g, 0.87 mmol) in EtOH 30 ml was heated and stirred to 75 °C for 1 h. After that, the Hmptrz ligand (0.1 g, 0.087 mmol was added to the mixture and further continuous stirring for 12 h. The colorless crystals of the complex were obtained after the colorless filtrate was kept to stand at room temperature for a day. The complex melts at 130–132°C.

Refinement top

All carbon H-atom of the triazole ring and the methyl group were placed in calculated positions (C-sp2—H = 0.93 and C-sp3= 0.96 Å) and were included in the refinement in the riding-model approximation, with Uiso(H) = 1.2Ueq(C) and Uiso(H) = 1.5Ueq(C), respectively. The H atom of triazole ring N atom is located in a difference map and restrained, N—H = 0.86 Å with Uiso(H) = 1.2Ueq(N).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
