The crystal and molecular structures of following selected multifunctional phenylsulfones were determined by X-ray diffraction methods using an Enraf-Nonius CAD4S diffractometer: a-(4-biphenylsulfonyl)acetophenone, (1); a-methyl-a-[4-(acetylamino)phenylsulfonyl]acetophenone, (II); 1,1-dichloro-2-phenyl-2-(4-allylsulfonylphenyl)ethane, (III); 1,1-dichloro-2-phenyl-2-(4-chlorosulfonylphenyl)ethane, (IV). The compound (I), (C20H16O3S), crystallizes in the monoclinic P21/c space group with unit cell dimensions: a =9.0527(6) A, b = 5.333(1) A, c= 34.286(2) A, b = 94.796(5)0. Analyzis of benzene-ring geometry leads to the conclusion that the bond angles and distances within the benzene rings of the four investigated structures seem normal, and only small deviations occur. In (I) all three rings are almost planar and the two rings the biphenyl are almost coplanar. The compound (II), (C17H17NO4S), crystallizes in the monoclinic P21/c space group with unit cell dimensions: a = 10.943(4) A, b = 8.566(2) A, c= 17.286(4) A, b = 90.57(3)0. Both rings are almost planar. The compound (III), (C17H14O2SCl2), crystallizes in the monoclinic P21/c space group with unit cell dimensions: a = 12.577(20) A, b = 18.961(2) A, c= 7.407(2) A, b = 103.83(2)0. Both rings are almost planar - the dihedral angles in ring A vary from -1.7o to 1.2o, and in ring B from -1,7o to 1,6o. The planes of the two rings are nearly perpendicular to each other.
