Comment top

1,3,4-Thiadiazole derivatives are important for medicinal chemistry due to their chemical and pharmaceutical properties (Nakagawa et al., 1996; Wang et al., 1999; Carvalho et al., 2004). Similar crystal structures of the 1,3,4-thiadiazole derivatives have been reported . As a part of our research, the title compound (I) has been synthesized, and herewith we present its crystal structure.

In (I) (Fig. 1), all geometric parameters are normal and comparable with those reported for related 1,3,4-thiadiazole derivatives (Li et al., 2011; Wang et al., 2010). Two thiadiazole rings form a dihedral angle of 46.3 (3)%. The dihedral angles between the benzene rings and attached thiadiazole rings are 0.8 (3) and 0.9 (3)° indicating the two rings are almost parallel. The same situation has been observed in the crystal structure of 1,4-bis(5-phenyl-1,3,4-thiadiazol-2-ylsulfanyl)butane (Li et al., 2011).

Experimental top

The title compound was synthesized by the reaction of the 1,1-dibromomethane (1.0 mmol) and 5-tolyl-1,3,4-thiadiazol-2-thiol (2.0 mmol) in ethanol (20 ml) at room temperature. Crystals of (I) suitable for single-crystal X-ray analysis were grown by slow evaporation of a solution in chloroform-enthanol (1:1).

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.
