(1Z)-1-(2,4-Dichloro-phen-yl)ethan-1-one semicarbazone

Abstract

In the title compound, C<inf>9</inf>H<inf>9</inf>Cl<inf>2</inf>N <inf>3</inf>O, the semicarbazone group is approximately planar, with an r.m.s deviation from the mean plane of 0.011 (2) Å. The dihedral angle between the least-squares planes through the semicarbazone group and the benzene ring is 38.76 (9)°. The crystal structure is further stabilized by N - H?O and C - H?O hydrogen bonding. © Fun et al. 2009.
