The pD-dependent stability of the [Co(acacen)(X)₂]⁺ derivatives. The observed trends of pD stability shows deviation from the pK_a of the free ligand. (A) the depletion of each derivative as a function of pD. Percentages of [Co(acacen)(X)₂]⁺ were determined in relation to the aquated species with reference to an internal standard. (B) the pD at which fifty percent of the starting material remained was determined in order to compare the pD stability of the [Co(acacen)(X)₂)]⁺ derivatives to resistance to aquation. The pD stability trend does not directly correlate to the pK_a stability trends of the free ligands. = 1, = 2, = 3, = 4, = 5, = 6.
