The Z(s-cis) isomer of 3-benzoyl-1-methylindole phenylhydrazone derive
d from a 3-aroyl-1-methylindole, was isolated. The structure consists
of two molecules with similar conformations in the asymmetric unit. Th
e dihedral angle (congruent-to 55-degrees) between the methyl indole s
ubstituent and the hydrazone moiety leads to a break in the delocaliza
tion.
