of non-Cp-based non-diketonato-based C2-symmetrical octahedral Ti(IV) complexes of dianionic diaminebis(phenolato) ligands, which are conveniently obtained as single isomers in quantitative yields, leads to appreciable cytotoxicity against colon and ovarian cells with a non-transferrin-dependent cell penetration mechanism. The ligand structural features including steric demands, symmetry, and aromaticity
