Magnetic properties of five copper(II) complexes of the formula [CuL 3(H2O)2] or [CuL4(H2O)] were investigated. These contain a Schiff-base L derived from salicylaldehyde and aminoacids. The ligand L is represented by four bonding isomers (1 through 4) and it is either tridentate (L3) or tetradentate (L4). The fifth ligand contains sulfonato group instead of the carboxyl one. Structurally, two complexes are monomers (1 and 4), one is a dimer (5), and two are polymers (2 and 3). Their magnetic behaviour is more complex: 1 behaves as an antiferromagnetic Heisenberg diad, 2 and 4 are ferromagnetic chains, 3 is a combined ferromagnetic/antiferromagnetic ladder (ribbon), and 5 exhibits a complex 3D-ordering with unusual temperature evolution of the effective magnetic moment.

Recently the rare-earth chelates have drawn special attention due to their possible application as laser materials.A variety of such lanthanon chelates with tridentate Schiff bases have been synthesized and studied in these laboratories.A survey of the literature has revealed that no work has been done on the Pr(III), Nd(III) and Sm(III) chelates of 2-(N-2-hydroxybenzylideneimino)ethane sulphonic acid (H2BE) and 3-(α-2-oxopentylideneimino) propanoic acid (H2OP) Schiff bases.The present paper describes the spectral and thermodynamic properties of these compounds.
