N2,N2′-Bis(2,2-dimethylpropanoyl)-benzene-1,3-dicarbohydrazide

In the molecular structure of the title hydrazide derivative, C18H26N4O4, the conformations of the two units of 2-(2,2-dimethyl-1-oxopropyl) hydrazide substituents are not planar; these two units are attached axially to the benzene ring with C(ortho)-C-C(=O)-N torsion angles of 28.1 (2) and 31.0 (2)degrees [where C(ortho) is the C atom at position 4 of the benzene ring relative to the substituent at position 3 or the C atom at position 6 of the benzene ring relative to the substituent at position 1, as appropriate]. The dihedral angles between the hydrazide units and the benzene ring are 62.66 (7) and 63.84 (7)degrees. In the crystal structure, molecules are arranged in an anti-parallel manner and are linked by N-H center dot center dot center dot O intermolecular hydrogen bonds and weak C-H center dot center dot center dot O intermolecular interactions into a three-dimensional network. The structure is further stabilized by a weak C-H center dot center dot center dot N intramolecular interaction.
