Stability of cubes M-73 in water noting their decomposition conditions. (a) Half-lives (t1/2), (b) ionic radii (IR, Å),111 and (c) ligand-exchange rates for water (kH2O, s–1)112 for the different metal ions are shown for comparison. †Fe-76 is low-spin, but kH2O for high-spin FeII is given as reference.
