Transition metal complexes of o-semiquinone (SQ) ligands have been studied
extensively over the past 25 years. A particularly interesting aspect of th
is coordination chemistry concerns magnetic interactions between paramagnet
ic metal ions and the radical anionic ligands. In this review we begin with
a survey of relatively simple complexes consisting of a paramagnetic metal
ion chelated by a single SQ ligand. Recent studies have revealed the impor
tance of SQ-SQ coupling through diamagnetic metals, and complexes of this c
lass are described in the second section of the review. Both interactions c
ombine to account for the often complicated magnetic properties of complexe
s containing multiple SQ ligands chelated to a paramagnetic metal ion. Rese
arch on these complexes is surveyed in the third section with a concluding
look toward polymeric SQ complexes. A review with 51 references.
