The molecular structures of compounds (Z)-1-phenyl-1-phenylseleno-2-(p-tolylsulfonyl) ethene 1 (C21H18O2SSe, Mr = 413.37) and 1,3-diphenyl-3-phenylseleno-2-(p-tolylsulfonyl)-2-propen-1-ol 2 (C28H24O3SSe, Mr= 519.49) were determined by single-crystal X-ray diffraction analyses. Crystal 1 crystallizes in monoclinic, space group P21/n with a = 12.574(4), b = 12.087(3),c = 13.132(4) A, β= 107.973(4)°, V= 1898.5(9) A3, Z=.4, Dc = 1.446 g/crm3,μ= 2.098 mm-1, λ=0.71073A, F(000) = 840, R = 0.0484 and wR = 0.1085. Crystal 2 crystallizes in monoclinic, space group P21/n with a = 7.0710(4), b = 14.6604(9), c = 24.3432(5) A, β= 94.76(1)°, V= 2514.8(3) A3,Z = 4, Dc = 1.372 g/cm3,μ = 1.603 mm-1, λ = 0.71073 A, F (000) = 1064, R = 0.0366 and wR =0.0573. The X-ray diffraction analysis shows that both of the title compounds are in Z-configuration.
