Abstract top

The title compound, C22H20BrN5OS, is a potent new fungicide. The planes of the phenyl and pyrozole rings are almost perpendicular, making a dihedral angle of 86.5 (4)°. There are two non-classical intermolecular C-H...O and C-H...N hydrogen bonds in the crystal structure.

Comment top

A variety of pyrazole and triazole heterocyclics could exhibit many activities. Meanwhile, heterocyclic compounds is an important developmental direction in medical (Gong et al., 2008) and pesticidal (Liu et al., 2007) chemistry.

In view of these facts and in continuation of our interest in the agriculture, we attempted to synthesize a series of amide derivatives, some of which have comparatively high fungicidal activity.

The molecular structure of title compound is showing in Fig.1. The x-ray analysis reveals that acetyl group is a planar with thio-ether group. The pyrozole ring is vertical with the benzene ring [dihedral angle 93.5 (4)°]. The packing of the structure is due to the weak intermolecular C-H..O and C-H..N H-bonds (Table 1. and Fig 2.).

Related literature top

For background to heterocyclic compounds, see: Gong et al. (2008); Liu et al. (2007). For the synthesis of 5-((3,5-dimethyl-1H-pyrazol-1-yl)methyl)-4-phenyl-4H-1,2,4-triazole-3-thiol, see: He et al. (2008).

Experimental top

The compound 5-((3,5-Dimethyl-1H-pyrazol-1-yl)methyl)-4-phenyl-4H-1,2,4 -triazole-3-thiol was synthesized according to the reference (He et al., 2008). Then added p-bromo-phenacyl bromide, potassium carbonate anhydrous and N,N-Dimethyl formamide was stirred at room temperature for 5 h, giving the title compound. Colorless single crystals suitable for x-ray diffraction were obtained by recrystallization from a mixture of ethyl acetate and petroleum ether.

Refinement top

The H atoms bonded to C and N atoms were positioned geometrically and refined using a riding model [aromatic C—H=0.93 Å, aliphatic C—H = 0.97 (2) Å, N—H=0.86 Å, Uiso(H) = 1.2Ueq(C)].

Special details top

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.
