Synthesis and Supramolecular Structure of 5,5'-Dihydroxy-2,2'-[1,1'-(propane-1,3-diyldioxydinitrilo)diniethylidyne]diphenol

摘要

The compound, 5,5'-dihydroxy-2,2'-[1,1'-(propane-1,3-diyldioxydinitrilo)dimethylidyne]diphenol with the molecular formula C_(17)H_(18)N2O6, assumes a cis conguration in which two phenoloxime moieties adopts an extended form. The dihedral angle between the two benzene rings of the molecule is 1.83(3)°. There are two fairly strong intramolecular O3-H3···N1 and O5-H5···N2 hydrogen bonds. Each compound molecule links three other neighboring molecules through two pairs of intermolecular O6-H6···O3 and O4-H4···O6 hydrogen-bonding interactions into an infinite wave-like 2D-layer supramolecular structure parallel to the ab crystallographic plane.
