1,3-Diphenylpropan-2-one (2,4-dinitrophenyl)hydrazone

abstract

In the title compound, C21H18N4O4, there is an intramolecular N-H center dot center dot center dot O hydrogen bond between the amino H atom and an O atom of the 2-nitro group of the adjacent benzene ring. The central benzene ring forms dihedral angles of 79.98 (7) and 82.88 (7)degrees with the two phenyl rings. In the crystal structure, molecules are linked into a three-dimensional network by weak C-H center dot center dot center dot N, C-H center dot center dot center dot O and C-H center dot center dot center dot pi interactions.
