摘要：

The title compound (C 10H 10N 2O 2 , M r =190.20), 1 methyl 5 phenylhydantoin (1 methyl 5 phenyl 2, 4 imidazolidinedione) was synthesized by the reaction of 2 hydroxy 2 methylthio acetophenone ( α benzoyl hemithioacetal) with methylurea in slightly acidic medium. The crystal was crystallized in the orthorhombic system, space group Pbca with parameters a=18.077(5), b=14.386(2), c=7.035(1), Z=8, V=1829(1) 3, D c =1.381 g/cm 3, μ (Mo Kα )=0.99cm -1, F(000)=800, R=0.040, R w =0.050 for 1395 observed reflections [ I>3σ(I )]. It consists of a planar benzene ring and an imidazole ring, whose dihedral angle is 96.32°. In the title crystal, the glide c related molecules ( x, 1/2-y, -1/2+z ) form chains, which are further related by the screw axis ( 1-x, 1/2+y, 1/2-z ), forming networks along the bc plane. The networks are centrosymmetrically packed (1- x, -y, -z).
