Abstract
Substituents at and adjacent
to the nitrogen atoms in 2,2?-bipyridyl and 1,10-phenanthroline are most likely
to cause drastic changes in the magnetic properties of complexes with these
ligands. Complexes of the N-oxides (2,2?-bipyridine 1,1?-dioxide, and 1,10-phenanthroline
1- oxide) with copper, and of 2-substituted phen
(substituent = Cl, CONH2) with iron(II)
are investigated, and a new one-step reaction to convert phno
into cphn is reported. The copper complex Cu(bpyo)Br2 shows antiferromagnetic interactions,
but other complexes Cu(bpyo)X2 (X = Cl, NO3) with this ligand are magnetically
normal, as are Cu(phno)Cl2 and Cu(phno)Br2. The complex [Fe(cphn)3]
(ClO4)2 lies near the high spin-low spin crossover for
iron(II), and its magnetic moment is normal at room temperature but falls with
decreasing temperature. The dioxide of phen appears
not to be formed by the literature method and no successful synthesis can be
reported here.
