In the title hydrate, C10H7N3OS·H2O, the essentially planar benzofuran [maximum deviation = 0.006 (1) Å] and 4,5-dihydro-1H-1,2,4-triazole [maximum deviation = 0.007 (1) Å] rings form a dihedral angle of 11.67 (6)°. In the crystal, O—H⋯N, O—H⋯S, N—H⋯O and N—H⋯S hydrogen bonds link the molecules into sheets lying parallel to the bc plane. Aromatic π–π stacking interactions [centroid–centroid distances = 3.5078 (8)–3.6113 (8) Å] are also observed.

A mixture of 2-(1-benzofuran-2-ylcarbonyl)hydrazinecarbothioamide (0.01 mol) and 10% KOH (10 ml) was refluxed for 3 h. The mixture was cooled to room temperature and then neutralized by the gradual addition of glacial acetic acid. The solid product obtained was collected by filtration, washed with ethanol and dried. It was then recrystallized using ethanol. Yellow blocks of the title compound were obtained by slow evaporation of the ethanolic solution.
O– and N-bound H atoms were located from a difference Fourier map. O-bound H atoms were fixed at their found positions (O–H = 0.8961 and 0.8208 Å), with Uiso(H) = 1.5 Ueq(O), whereas N-bound H atoms was refined freely [N–H = 0.844 (18) and 0.90 (2) Å]. The remaining H atoms were positioned geometrically [C–H = 0.93 Å] and refined using a riding model with Uiso(H) = 1.2 Ueq(C). In the final
one outlier (1 1 1) was omitted.The 1,2,4-triazole nucleus has been incorporated into a wide variety of therapeutically interesting compounds. Several compounds containing 1,2,4-triazole rings are well known as drugs. For example, fluconazole is used as an antimicrobial drug (Shujuan et al., 2004), whereas vorozole, letrozole and anastrozole are non-steroidal drugs used for the treatment of cancer (Clemons et al., 2004) and loreclezole is used as an anticonvulsant (Johnston, 2002). Similarly substituted derivatives of triazole possess comprehensive bioactivities such as antimicrobial, anti-inflammatory, analgesic, antihypertensive, anticonvulsant and antiviral activities (Wei et al., 2007). We now report the synthesis and
of the title compound.The
of the title compound, (Fig. 1), consists of one 5-(1-Benzofuran-2-yl)-2,4-dihydro-3H-1,2,4-triazole-3-thione molecule and one water molecule. The benzofuran ring (O1/C3–C10) and the 4,5-dihydro -1H-1,2,4-triazole ring (N1–N3/C1/C2) are essentially planar with maximum deviations of 0.006 (1) Å at atom O1 and 0.007 (1) Å at atom N3, respectively. The dihedral angle between the benzofuran and 4,5-dihydro- 1H-1,2,4-triazole rings is 11.67 (6)°. Bond lengths and angles are within normal ranges and comparable to the related structures (Jing et al., 2012; Fun et al., 2011; Abdel-Aziz et al., 2011).The crystal packing is shown in Fig. 2. The molecules are linked via O1W—H1OW···N2, O1W—H2OW···S1, N1—H1N1···O1W and N3—H1N3···S1 hydrogen bonds (Table 1) into two-dimensional networks parallel to bc-plane. π–π interactions of Cg1···Cg1 = 3.6113 (8) Å (symmetry code: 1 - x, -y, 1 - z), Cg1···Cg2 = 3.5078 (8) Å (symmetry code: 2 - x, -y, 1 - z), Cg2···Cg3 = 3.5881 (8) Å (symmetry code: 1 - x, -y, 1 - z) and Cg3···Cg2 = 3.6056 (8) Å (symmetry code: 2 - x, -y, 1 - z) further stabilized the [Cg1, Cg2 and Cg3 are the centroids of the O1/C3–C5/C10, N1–N3/C1/C2 and C5–C10 rings, respectively].

Experimental. The crystal was placed in the cold stream of an Oxford Cryosystems Cobra open-flow nitrogen cryostat (Cosier & Glazer, 1986) operating at 100.0 (1) K. |
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. |

The 1,2,4-triazole nucleus has been incorporated into a wide variety of therapeutically interesting compounds. Several compounds containing 1,2,4-triazole rings are well known as drugs. For example, fluconazole is used as an antimicrobial drug (Shujuan et al., 2004), whereas vorozole, letrozole and anastrozole are non-steroidal drugs used for the treatment of cancer (Clemons et al., 2004) and loreclezole is used as an anticonvulsant (Johnston, 2002). Similarly substituted derivatives of triazole possess comprehensive bioactivities such as antimicrobial, anti-inflammatory, analgesic, antihypertensive, anticonvulsant and antiviral activities (Wei et al., 2007). We now report the synthesis and crystal structure of the title compound.
The asymmetric unit of the title compound, (Fig. 1), consists of one 5-(1-Benzofuran-2-yl)-2,4-dihydro-3H-1,2,4-triazole-3-thione molecule and one water molecule. The benzofuran ring (O1/C3–C10) and the 4,5-dihydro -1H-1,2,4-triazole ring (N1–N3/C1/C2) are essentially planar with maximum deviations of 0.006 (1) Å at atom O1 and 0.007 (1) Å at atom N3, respectively. The dihedral angle between the benzofuran and 4,5-dihydro- 1H-1,2,4-triazole rings is 11.67 (6)°. Bond lengths and angles are within normal ranges and comparable to the related structures (Jing et al., 2012; Fun et al., 2011; Abdel-Aziz et al., 2011).
The crystal packing is shown in Fig. 2. The molecules are linked via O1W—H1OW···N2, O1W—H2OW···S1, N1—H1N1···O1W and N3—H1N3···S1 hydrogen bonds (Table 1) into two-dimensional networks parallel to bc-plane. π–π interactions of Cg1···Cg1 = 3.6113 (8) Å (symmetry code: 1 - x, -y, 1 - z), Cg1···Cg2 = 3.5078 (8) Å (symmetry code: 2 - x, -y, 1 - z), Cg2···Cg3 = 3.5881 (8) Å (symmetry code: 1 - x, -y, 1 - z) and Cg3···Cg2 = 3.6056 (8) Å (symmetry code: 2 - x, -y, 1 - z) further stabilized the crystal structure [Cg1, Cg2 and Cg3 are the centroids of the O1/C3–C5/C10, N1–N3/C1/C2 and C5–C10 rings, respectively].
