(Received 21 May 2013; accepted 27 May 2013; online 31 May 2013)

The self-assembly of an angular 2,5-bis­(pyridin-2-yl)-1,3,4-thia­diazole ligand (L) with silver nitrate (AgNO3) produced a new dinuclear silver(I) coordination complex, [Ag2(C12H8N4S)2(NO3)2]·4H2O, which crystallizes with two Ag atoms bridged by two L ligands. The Ag atom is surrounded by four N atoms of L and by one O from the nitrate anion defining a distorted square pyramid. The atoms comprising the dication are nearly coplanar, with an r.m.s. deviation of 0.1997 Å. Mol­ecules are linked by C—H⋯O and O—H⋯O hydrogen bonds through nitrate anions and water mol­ecules, forming a two-dimensional porous network. The overall structure involves stacking of Ag complex layers along the b axis. The cohesion in the three-dimensional architecture is ensured by O⋯Ag inter­actions.

Comment top

The design and construction of novel coordination polymers are very important parts of crystal engineering not only for the purpose of generating functional materials (Maspoch et al., 2004) but also for their fascinating structures (Brammer, 2004). So far, the design and synthesis of new ligands with various coordinating modes, the exploration of synthetic methods to construct coordination polymers, and investigation on the effect of various factors upon architectures have greatly contributed to this field (Ghosh et al., 2004). The compound 2,5-bis(2-pyridyl)-1,3,4-thiadiazole was usually used as a bidentate ligand to form five-atom ring complexes and sometimes it coordinates two metal atoms by four nitrogen atoms as double-bidentate ligand. The structures of monomeric complexes of the neutral 2,5-bis(2-pyridyl)-1,3,4-thiadiazole derivative with Cu2+ (nitrate, perchlorate and trifluoromethanesulfonate) and Ag+ (SbF6-) have been previously reported (Bentiss et al., 2012; Niu et al., 2009). Recently, the study of the new di-nuclear silver(I) coordination complexes with 2,5-bis(2-pyridyl)-1,3,4-thiadiazole showed that the supramolecular structures of its silver complexes can change with the size of counter-anions of the same polyhedron (Niu et al., 2009). As a continuation of our work, in this contribution, we report here the synthesis and the single-crystal structure determination of the new dimeric complex formed by 2,5-bis(2-pyridyl)-1,3,4-thiadiazole (L) with silver nitrate as counter ions.

The asymmetric unit of the title compound, [2,5-bis(2-pyridyl)-1,3,4- thiadiazole]silver(I) nitrate, dihydrate is doubled by the application of a centre of inversion, resulting in a Ag2-containing dimeric complex. The structure shows the silver cation in a distorted square pyramid site formed by four nitrogen atoms belonging to one organic ligand and an O atom of a nitrate anion (Fig. 1). Each ligand molecule is build up by two six-membered rings linked through a five-membered ring. The two silver atoms and ligands are nearly coplanar, with a r.m.s. deviation of 0.1997 Å. The molecules are linked together by C–H···O and O–H···O hydrogen bonds through nitrate and water molecules, forming a two-dimensional porous network. The overall structure involves stacking of Ag complex layers nearly along the b axis. The cohesion in the crystal is ensured by O3–Ag1 interaction (Fig. 2 and Table 2).

Experimental top

2,5-Bis(2-pyridyl)-1,3,4-thiadiazole ligand (L) was synthesized as described previously by Lebrini et al. (2005). AgNO3 (0.75 mmol, 0.13 g) in water (5 ml ) was added to L (0.21 mmol, 50 mg) dissolved in ethanol (13 ml). The resulting solution was stirred for 30 min. The solution was filtered and allowed to stand at ambient temperature. After seven days, yellow blocks crystallized. Crystals were washed with water and dried under vacuum (yield 34%). These crystals were used as isolated for single-crystal X-ray analysis. Anal. Calc. for C24H24Ag2N10O10S2. C, 37.60; H, 3.13; N, 18.28 S, 8.37; Found: C, 37.69; H, 3.17; N, 18.21; S, 8.34.

Refinement top

H atoms were located in a difference map and treated as riding with C—H = 0.93 Å (aromatic) and O—H = 0.86 Å (water) with Uiso(H) = 1.2 Ueq(aromatic) and Uiso(H) = 1.5 Ueq (water). The reflections (001), (01–1), (0–11) and (010) are removed from the refinement because they are affected by the beam stop.

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