Arene ruthenium, rhodium and iridium complexes containing benzamide derivative ligands: Study of interesting bonding modes, antibacterial, antioxidant and DNA binding studies

The benzamide derivative ligands of benzothiazole (L1) and benzimidazole (L2) upon reaction with halide bridged metal precursors of platinum group yielded a series of complexes (1-6) formulated as [(arene)M(κ1(N)-L)Cl2], where, L = L1 and L2, M = Ru, Rh and Ir, arene = Cp*, p-cymene. Structural studies revealed the bonding of the ligands to the metal centers takes through the nitrogen donor atom of the benzothiazole and benzimidazole moiety in a...
