Crystal Structure of Z-2-Amino-1-phenyl-3-phenylsulfonylprop-2-en-1-one

Abstract

Z-2-Amino-1-phenyl-3-phenylsulfonylprop-2-en-1-one crystallizes in the orthorhombic space group Pna2₁ with a = 9.3161(8), b = 9.9450(8), c = 15.2434(13)Å, V = 1412.3(2)ų and Z = 4. The structure was solved by direct methods (SHELXS-97) and refined to a final R value of 0.028 for 2799 reflections [R(int) = 0.029]. The title compound has a Z geometry about the ethene double bond. Intermolecular hydrogen bond formation between the nitrogen hydrogen atoms and the oxygen atoms of the sulfone as well as the NH₂ hydrogen atoms and the carbonyl groups leads to a polymeric structure.
