Abstract
The compound 4,4'-dichloro-6,6'-dibromo-2,2'-[(hexane-1,6-diyldioxy)bis(nitrilomethylidyne)]diphenol with the molecular formula C20H20N2O2Br2Cl2, is central symmetric structure and two phenyl rings in each molecule are parallel to each other. Two intramolecular O2-H2···N1 hydrogen bonds involving the hydroxyl groups and oxime N atoms generate two S(6) ring motifs in each molecule. In the crystal structure, each molecule interlinks two neighboring molecules into a 1D infinite chain supramolecule through two intermolecular C8-H8···Cl1 hydrogen bonds.
