(1Z)-1-(2,4-Dichlorophenyl)ethan-1-one semicarbazone
Abstract
In the title compound, C9H9Cl2N3O, 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.
