Abstract:
The asymmetric unit of the title compound, C16H12Cl4N2O2, comprises half of a potentially tetradentate Schiff base ligand, located about a twofold rotation axis which bisects the central C—C bond of the ethane-1,2-diamine group. In the solid state, the compound exists in the zwitterionic form. There are two intramolecular N—H⋯O hydrogen bonds making S(6) ring motifs. In the crystal, molecules are linked by C—H⋯O hydrogen bonds, forming two-dimensional frameworks which lie parallel to (100). There are also short Cl⋯Cl [3.4395 (9) Å] contacts present.
