Terdentate ligands, mononuclear complexes

The structures of the complexes formed by the Schiff bases (162) depend upon the nature of R when R is a simple alkyl or aryl group the complexes are of the type CuL2 with an essentially planar structure,701 but when R contains a potential donor, CH2CH20 or CH2CH2CH20, a multinuclear structure results, whilst when R = MeC02, the ligand is terdentate, and produces a mononuclear complex.
