In a dry 100 ml Erlenmeyer flask were placed benzaldehyde (10 mmol), 4-methoxythiophenol (10 mmol), iodine (15 mol %) and dichloromethane (DCM; 15 ml). The reaction mixture was stirred at room temperature for an hour. The reaction was monitored by TLC and after the completion of reaction the iodine utilized was removed from the product by treating it with aqueous sodium thiosulfate solution. The final product was extracted into DCM (2 x 20 ml). The crude reaction mixture was purified by
on silica gel using ethyl acetate/hexane as the eluents. Final yields: 93%; M.pt: 322 (1) °K. Suitable single crystals of the title compound were grown from its ethanol/tetrahydrofuran mixture (1:1).H atoms were placed in their geometrically expected positions and refined in the riding-model approximation [Csp2—H = 0.93 Å, C(methine)—H = 0.98 Å and C(methyl)—H = 0.96 Å, and with Uiso(H) = 1.2Ueq(parent) or 1.5Ueq(Cmethyl)]. The torsion angles for the methyl group H atoms were set with reference to a local difference Fourier calculation. The reflection (100), truncated by the beam stop, was omitted during the final cycles of refinement.

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. |

A search in Cambridge Structural Database (CCDC; version 5.31; Allen, 2002) revealed four similar crystal structures (Farrugia et al., 2000). The title compound, Fig. 1, forms a propeller-shaped structure with the tetrahedral carbon of the phenylmethyl moiety as the central hub and methoxybenzene and phenyl moieties as radiating blades. Short C—H···π contacts stabilize the structure, Table 1.
