Synthesis and Single Crystal X-Ray Structure of New (2E)-2-[3-(1H-Imidazol-1-yl)-1-phenylpropylidene]-N-phenylhydrazinecarboxamide

Abstract

Synthesis, spectroscopic characterization and X-ray crystal structure of a new (2E)-2-[3-(1H-imidazol-1-yl)-1-phenylpropylidene]-N-phenylhydrazinecarboxamide (4) are reported. The stereochemistry of the title compound 4, C19H19N5O, about the imine bond [1.296 (4) Å] was assigned to have (E)-configuration. In the urea moiety, the N–H entities are trans to each other, and one of these forms is an intramolecular N–H⋯H hydrogen bond. The compound crystallizes in the monoclinic space group P21/c with a = 5.8093 (2) Å, b = 20.5575 (6) Å, c = 14.0355 (5) Å, α = 90.00°, β = 97.365° (2), γ = 90.00°, V = 1662.36 (10) Å3, and Z = 4. The molecules are packed in crystal structure by weak intermolecular hydrogen interactions.
