six-coordinate geometry. The ligand and its complexes (1–14) were screened for their antimicrobial, antitumor, cytotoxic and antileishmanial activities and found to be biologically active. The ligand and its complexes bind to DNA via intercalative interactions resulting in hypochromism and minor bathochromic shifts as confirmed by UV–visible spectroscopy. Based on in vitro studies such as the potato
