The nickel complex 2 Ni shows reactivity about 10 3 times greater than that of the cobalt analogue 2 Co . The oxidation ability of the M III (m-O) 2 M III core should be affected by the hindered Tp R ligand system, which can stabilize the 2 oxidation state of the metal centers.
## Abstract ## Purpose To test the hypothesis that catheterβdirected intraarterial (IA) contrast agent injection increases tumor enhancement and conspicuity compared to intravenous (IV) injection. ## Materials and Methods Eight VX2 liver tumors were grown in five rabbits. After positioning a cat
