In the title Schiff base compound, C13H9Cl2NO, the molecule displays an E conformation about the imine C=N double bond, with a dihedral angle of 8.09 (11)° between the two benzene rings. In the crystal, molecules are linked by a single O—H...O hydrogen bond, giving one-dimensional chains which extend along (100).

Schiff Base Metal Complexes

A series of novel (E)-2-((Tetrazolo[1,5-a]quinolin-4-ylmethylene)amino)phenol Cu(II), Co(II), Ni(II), Zn(II) and Mn (II) metal complexes have been synthesized 1:1 metal to ligand ratio, and these complexes were characterized by using analytical data such as FT-IR, UV-visible, Mass spectroscopy, SEM, EDX, TGA and magnetic moment measurements. The ligand and all the metal complexes were tested in vitro antimicrobial activity and DNA cleavage studies.

In the mononuclear title complex, [HgCl2(C16H12N2O)], synthesized from the phenolic Schiff base 4-[(quinolin-2-ylmethylidene)amino]phenol (QMAP), the coordination geometry around Hg2+is distorted tetrahedral, comprising two Cl atoms [Hg—Cl = 2.3565 (12) and 2.5219 (12) Å] and two N-atom donors from the QMAP ligand,viz.one imine and the other quinoline [Hg—N = 2.392 (2) and 2.237 (2) Å, respectively]. In the crystal, O—H...Cl hydrogen bonds generate a chain structure extending along thec-axis direction. Weak C—H...Cl and π–π stacking interactions [minimum ring centroid separation = 3.641 (3) Å] give an overall layered structure lying parallel to (001).
