Crystal Structure and Hirshfeld Surface Analysis of 2-{[(4

Abstract

The title compound, C13H9IN2O3, was synthesized by a condensation reaction between 2-hydroxy-5-nitrobenzaldehyde and 4-iodoaniline, and crystallizes in the orthorhombic space group Pna2(1). The 4-iodobenzene ring is inclined to the phenol ring by a dihedral angle of 39.1 (2)degrees. The configuration about the C=N double bond is E. The crystal structure features C-H center dot center dot center dot O hydrogen-bonding interactions. A Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the packing arrangement are O center dot center dot center dot H/H center dot center dot center dot O (26.9%) and H center dot center dot center dot H (22.0%) interactions.
