Abstract

The synthesis and X-ray crystal structure of benzil dihydrazone are reported. It is found to be a twisted molecule with a N[double bond, length as m-dash]C–C[double bond, length as m-dash]N torsion angle of ∼70°. The H-bonding pattern in the crystal gives rise to columnar single helical supramolecular structure. In contrast, diacetyl dihydrazone, a planar molecule, has a H-bonded 3-D network with pores in the solid state.
