Studies of oxime complexes
Published 1981“…The complexes Fe(Ppo)2.H2O, Fe(Ppo)2 .2py and Fe(po)2.H2O were found to be high spin. This property contrasts the behaviour of iron(II) complexes derived from 2-nitrosophenols, which are low spin, and is rationalised in terms of conjugation effects and the bonding character of the pyrazol-4, 5-dione monooxime ligand. …”
