Synthesis and biological evaluation of some new class of benzothiazole–pyrazole ligands containing arene ruthenium, rhodium and iridium complexes

Metal complexes 1–9 have been synthesized by reacting the benzothiazole–pyrazole derivative ligands (L1, L2 and L3) with the metal precursors of ruthenium (Ru), rhodium (Rh) and iridium (Ir). The complexes have been isolated as cationic mononuclear N ∩ N chelating metal complexes having the general formula as [(arene)M(κ2(N∩N)-L)Cl]PF6 where L = L1, L2 and L3, M = Ru, Rh and Ir, arene = p-cymene, Cp*. Structural studies revealed the mode of...
