Abstract
The dication [Ni(meso-L1)]2+, (1), [the NII complex of the meso diastereoisomer of the ligand 1,3-bis{(o-aminophenyl)phenylphosphino}propane, meso-L1] on deprotonation gives the neutral complex, [Ni(meso-L1–2H)], (2), with a cis-disposition of the two amido groups which undergo facile alkylation with propane-1,3-ditoluene-p-sulphonate to give [Ni(L2–2H)], (3), a complex of the new P2N2 macrocycle meso- L2; X-ray structure analyses of the nitrate salt of (1), L2, and (3) confirm the meso-configuration of the ligands.Keywords
