Role of the (pseudo)halido ligand in ruthenium(ii) p-cymene α-amino acid complexes in speciation, protein reactivity and cytotoxicity

Replacement of the labile chlorido ligand with (pseudo)halides in Ru( ii ) p -cymene α-amino acid complexes determines their speciation in water and in cell culture medium and reactivity with cytochrome c; yet does not confer cytotoxicity.
