(Received 13 August 2012; accepted 1 September 2012; online 8 September 2012)

The title two-component mol­ecular crystal, C10H8N2·C2H4N4S, was obtained unexpectedly by reaction of Zn(NO3)2·6H2O, NH4BF4 with 3-amino-1,2,4-triazole-5-thione (3-AMT) and 4,4′-bipyridine in water. The dihedral angle between the pyridine rings in the 4,4′-bipyridine molecule is 17.00 (13)°. In the crystal, N—H⋯N and N—H⋯S hydrogen bonds between the components lead to the formation of a three-dimensional network. Furthermore, the structure features face-to-face π–π stacking inter­actions between the 4,4′-bipyridine and triazole rings, with a centroid–centroid distance of 2.976 (2) Å.

Comment top

Supramolecular compounds have received much attention due to their structural diversities and potential applications as new materials. The ligand 3-amino-1,2,4-triazole-5-thione(3-AMT), with one –SH, one –NH2 group and three potential coordination nitrogen atoms of triazole, is excellent in building metal-organic supramolecular structures (Hao et al., 2010; Ma et al., 2008; Rakova et al., 2003). Moreover, its nitrogen atom and sulfur atom may be involved in hydrogen bonding (Deng et al., 2005; Downie et al., 1972).

The title compound was unexpectedly obtained in the course of synthesizing 3-AMT-Zn(II) complexes. The molecular structure of the title compound is shown in Fig.1. The crystal structure of C2H2N4S.C10H8N2 has been determined at room temperature. The compound has the space group P2(1)/c, with a = 13.5151 (12), b = 6.9680 (5), c = 16.5529 (14) Å and beta = 122.385 (2)°. The hydrogen bonds are formed between the N—H donors of 3-AMT and the nitrogen atoms from 4,4'-bipyridine and 3-AMT, and the atoms N6, N5 and N3 act as acceptors with d(N1···O6) = 2.828 (3) Å, d(N2···N5) = 2.829 (3) Å, d(N4···N3) = 3.151 (3) Å, N1—H1···N6 =171°, N2—H2···N5 =163° and N4—H4A···N3 =159°, which are just similar to the corresponding distances and angles in the compound of C10H8N2.2C2H3N3S2 (Deng et al., 2005). Intermolecular hydrogen bonds N—H···N and N—H···S between the components lead to the formation of a three-dimensional network (Fig.2). Furthermore, the structure is stabilized by the face to face π-π stacking interactions between 4,4'-bipyridine and triazole ring, with the centroid-centroid distance of 2.976 (2) Å.

Experimental top

A mixture of 3-AMT (0.6 mmol), NaOH (0.6 mmol), NH4BF4 (0.6 mmol), Zn(NO3)2.6H2O (0.3 mmol), 4,4'-bipyridine (0.3 mmol) and water (10 mL) was placed in a Teflon-lined stainless steel vessel (20 mL) and heated at 150°C for 72 h and then cooled to room temperature at a rate of 5°C/h.The filtrate was evaporated slowly at room temperature for 2 weeks to yield yellow crystalline products.

Refinement top

The final refinements were performed by full matrix least-squares methods with anisotropic thermal parameters for non-hydrogen atoms on F2. All hydrogen atoms were located in the calculated sites and included in the final refinement in the riding model approximation with displacement parameters derived from the parent atoms to which they were bonded (Uiso(H) = 1.2Ueq).

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.
