Copper(ii) complexes with benzhydrazone-related ligands: synthesis, structural studies and cytotoxicity assay

The present study reports the synthesis and characterization of copper(ii) complexes with benzhydrazone-related ligands. They were screened for their cytotoxic activityin vitroin THP-1 and HepG2 human cancer cell lines.

Bis[μ-4-hydr-oxy-N'-(4-meth-oxy-2-oxido-benzyl-idene)benzohydrazidato]bis-[pyridine-copper(II)]

In the title compound, [Cu₂(C₁₅H₁₂N₂O₄)₂(C₆H₅N)₂], each Cu^II atom is chelated by the tridentate doubly deprotonated Schiff base and a pyridine mol­ecule in a nearly planar environment (r.m.s. deviation for all non-H atoms = 0.107 Å). The metal ions are bridged by one O atom from the symmetry-related Schiff base ligands, forming a centrosymmetric dinuclear copper(II) complex. The dimeric complex is linked to another dimer via weaker Cu—O inter­actions and also O—H⋯N hydrogen bonds.
