Paramagnetic species, enantiomeric

Similar to other cyclen-based macrocycles (e.g. DOTA), two enantiomeric forms defined by a clockwise or counter-clockwise spiraling of the methyl-enephosphonate arms may be envisaged for [Ln(DOTP)] complexes. However, unlike DOTA complexes, [Ln(DOTP)] complexes are believed to exist in solution as one enantiomeric pair. An isomeric form of [Tm(DOTP)] corresponding to the minor isomer observed for [Yb(DOTA)] (8-coordinate SAP geometry) was inferred by comparison of the paramagnetic shifts of the two species... [Pg.44]
