(E)-1-(4-Fluoro-phen-yl)ethan-1-one semicarbazone

Abstract

In the title compound, C9H10FN3O, the semicarbazone group is nearly planar, with the maximum deviation of 0.044 (1) for one of the N atoms. The mean plane of semicarbazone group forms a dihedral angle of 30.94 (4) with the benzene ring. The mol-ecules are linked into a supra-molecular chain by N - H?O hydrogen bonds formed along the c axis. The crystal structure is further stabilized by weak inter-molucular C - H?? inter-actions; the closest C?Cg contact is 3.6505 (11) .
