Abstract
Two crystalline forms of 1,4-dimethyl-2-(4-(methyl-sulfonyl) styryl)benzene (1) and 1,3-diisopropyl-2-(4-(methyl-sulfonyl)styryl) benzene (2) were obtained and their structures were determined by X-ray diffraction technique. Both compound 1 and 2 crystallized in a triclinic space group P-1 with cell parameters a = 5.375(2) Å, b = 18.402(7) Å, c = 23.109(9) Å, α = 95.838(4), β = 94.579(4)º, γ = 91.407(4)º, V = 2265.3(15) Å3, Dc = 1.264 g/cm3, Z = 6, and a = 9.332(7) Å, b = 11.028(8) Å, c = 11.574(9) Å, α = 111.795(6)º, β = 94.162(8)º, γ = 92.177(7)º, V = 1100.3(14) Å3, Dc = 1.161 g/cm3, Z = 2, respectively. Both of them display a trans-configuration with respect to the C=N double bond. Their crystal packings are stabilized by weak C–H···O hydrogen bonds and van der Waals interactions.
