Abstract
Studies of hydrogen bonding between water and bis(pentane-2,4-dionato)-beryllium(II) (Be(acac)2), bis(3-methylpentane-2,4-dionato)-beryllium(II) (Be(Meacac)2), and tris(pentane-2,4-dionato)cobalt(III) (Co(acac)3) have been undertaken in [2H]6-benzene solution using1H NMR and infra-red spectroscopy. Equilibrium constants for 1:1 water-metal complex hydrates, and approximate enthalpies and entropies of reaction, have been measured from the1H NMR data. The equilibrium constants are larger for Co(acac)3 than for the Be(II) complexes, in line with previous data for the partition of these chelates between water and aliphatic hydrocarbon solvents.
