Bis(imino)pyridine (NNN)‐type ligand [(PyPhime‐Cina) = 2,6‐bis((E)‐1‐phenyl‐2‐((E)‐3‐phenylallylidene)hydrazinyl)pyridine] was synthesized, and a new family of metal complexes [Mn(PyPhime‐Cina)Cl2] ( 1 ), [Fe(PyPhime‐Cina)Cl2] ( 2 ), [Co(PyPhime‐Cina)Cl2] ( 3 ), [Ni(PyPhime‐Cina)Cl2] ( 4 ), and [Cu(PyPhime‐Cina)Cl2] ( 5 ), derived from the ligand, have been synthesized and characterized. Molecular structures of the ligand and complexes 1‐5 were determined using X‐ray crystallography. Electronic properties and frontier molecular orbitals of the complexes were investigated by DFT and TD‐DFT calculations. DNA interaction studies were evaluated by UV‐visible absorption, fluorescence and circular dichroism spectral studies which indicated noncovalent binding of complexes with CT‐DNA. Hirshfeld surface analysis of all the complexes was studied to know the weak interaction present in the molecules.
