In the title compound, C12H11Cl3N2O4, the dihedral angle between the aromatic ring and the hydrazine (NH—N=C) grouping is 52.2 (3)°. The butanedioate groups exhibit planar conformations. An intramolecular N—H⋯O hydrogen bond links the N—H group of the hydrazine to one of the methoxy groups of the butanedioate moiety. In the crystal, molecules are linked by C—H⋯O hydrogen bonds and π–π interactions are also observed [centroid–centroid separation = 3.535 (1) Å].
In this paper, we report translational order parameter in two liquid crystalline compounds, namely, p-cyanobenzylidene p-nonyloxyaniline and p-decyloxybenzylidene p-butylaniline at different temperatures in their smectic phase(s). Translational order parameter has been estimated using the recorded X-ray intensity data. The results obtained are compared and discussed.
In the title compound, C18H21N3O2, the dihedral angle between the benzene rings is 68.85 (11)°. In the crystal, the molecules are linked by C—H⋯O and N—H⋯O hydrogen bonds, as well as weak C—H⋯π contacts, forming a three-dimensional supramolecular architecture.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
