Diethyl (E)-2,3-bis[(E)-(2-methyl-2-phenylhydrazin-1-ylidene)methyl]but-2-enedioate

Abstract

The complete molecule of the title compound, C24H28N4O4, is generated by crystallographic inversion symmetry. The ethyl side chain is disordered over two sets of sites in a 0.57 (4):0.43 (4) ratio. The dihedral angles between the methylidene group and the phenyl ring and ester side chain (major conformation) are 7.61 (8) and 86.95 (8)°, respectively. In the crystal, molecules are linked via C—H...O hydrogen bonds, forming corrugated sheets lying parallel to (010).
