A suspension of 5-phenyl-1,3,4-oxadiazole-2-thiol (3.0 mmol) and 2,4,6-trimethyl-1,3,5-tribromomethyl benzene (1.0 mmol) in ethanol (10 ml) was stirred at room temperature. The reaction progress was monitored via TLC. The resulting precipitate was filtered off, washed with cold ethanol, dried and purified to give the target product as white solid in 80% yield. Crystals of (I) suitable for single-crystal X-ray analysis were grown by slow evaporation of a solution in chloroform-ethanol (1:1).
All H atoms were positioned geometrically and refined as riding (C—H = 0.95–0.99 Å) and allowed to ride on their parent atoms, with Uiso(H) =1.2-1.5Ueq of the parent atom.
1,3,4-Oxadiazole derivatives have wide applications in medicine, industry and coordination chemistry, so they are under intensive studies (Al-Talib et al., 1990; Wang et al., 2005; Zhang et al., 2007). Recently, novel thio-based ligands with multi-armed tripodal geometry were synthesized, and these ligands demonstrated their significance in the supramolecular studies (PrakashaReddy & Pedireddi, 2007 and references therein). Herewith we present the title compound (I), where the 2,4,6-trimethylbenzene center contains three 5-phenyl-1,3,4-oxadiazol-2-ylsulfanylmethyl arms.
In (I) (Fig.1), two phenyloxadiazole fragments - C10—C15/C8/C9/N1/N2/O1 (A) and C20—C25/C18/C19/N3/N4/O2 (B), respectively - are situated on the one side of the central benzene ring (C1—C6), while the third phenyloxadiazole fragment - C30—C35/C28/C29/N5/N6/O3 (C) - is situated on the other side of the central benzene ring. In A and B, the oxadiazole rings are almost coplanar with the attached phenyl rings forming dihedral angles of 1.5 (2) and 2.4 (2)°, respectively. The terminal phenyl rings are roughly orthogonal to the plane of the central benzene ring with dihedral angles of 82.0 (2), 89.2 (2) and 72.4 (2)°, respectively. The crystal packing exhibits weak intermolecular C—H···N interactions (Table 1).

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. |

1,3,4-Oxadiazole derivatives have wide applications in medicine, industry and coordination chemistry, so they are under intensive studies (Al-Talib et al., 1990; Wang et al., 2005; Zhang et al., 2007). Recently, novel thio-based ligands with multi-armed tripodal geometry were synthesized, and these ligands demonstrated their significance in the supramolecular studies (PrakashaReddy & Pedireddi, 2007 and references therein). Herewith we present the title compound (I), where the 2,4,6-trimethylbenzene center contains three 5-phenyl-1,3,4-oxadiazol-2-ylsulfanylmethyl arms.
In (I) (Fig.1), two phenyloxadiazole fragments - C10—C15/C8/C9/N1/N2/O1 (A) and C20—C25/C18/C19/N3/N4/O2 (B), respectively - are situated on the one side of the central benzene ring (C1—C6), while the third phenyloxadiazole fragment - C30—C35/C28/C29/N5/N6/O3 (C) - is situated on the other side of the central benzene ring. In A and B, the oxadiazole rings are almost coplanar with the attached phenyl rings forming dihedral angles of 1.5 (2) and 2.4 (2)°, respectively. The terminal phenyl rings are roughly orthogonal to the plane of the central benzene ring with dihedral angles of 82.0 (2), 89.2 (2) and 72.4 (2)°, respectively. The crystal packing exhibits weak intermolecular C—H···N interactions (Table 1).
