 Title    Lanthanide(III) Complexes of Oxamic Acid  
 Abstract    The preparation, for the first time, of the deprotonated complexes of oxamic acid with Ce(III), Pr(III), Nd(III), Sm(III), Eu(III), Dy(III), Ho(III) and Yb(III) is reported. Properties, analytical results, conductometric measurements, magnetic moments and spectral data (IR and diffuse reflectance spectra) are discussed in terms of possible struc-tural types and the nature of the bonding. Oxamic acid acts as a bidentate non-bridging ligand.

 Title    Binding of Cations to 4 f Metal Ions : Preparation and Properties of Lanthanide(III) Complexes Containing the Phenelzinium(l+) Cation as a Ligand  
 Abstract    Treatment o f Ln2(S 0 4)3 • nH 20 (Ln = La, Ce, Pr, Nd, Sm. Eu, Gd ; n -8, 9) with phenelzine dihydrogen sulfate, (phzH2) S 0 4, in 1 N H2S 0 4 yields polymeric complexes with the general formula [L n (S 0 4)2(H 20) 2(phzH)], which contain the phzH+ cation as a ligand. The compounds have been characterized by elem ental analyses, X-ray powder patterns, thermal methods, magnetic susceptibilities and spectroscopic (IR, Raman, electronic diffuse reflec­ tance and solid-state emission f -f spectra) studies. The prepared complexes most probably consist of 7-coordinated units, formed by four bridging bidentate sulfato groups, two terminal aqua m olecules and one cationic phzH+ ligand.

 Title    Four Novel N 3 O 4 Donor Macrocycles and their Lanthanide(III) Complexes  
 Abstract    A new series of lanthanide(III) complexes with two novel Schiff-base macrocycles, L 1 and L2, containing a N3O4 donor set have been prepared by cyclocondensation of 2,6-bis(2-formylphen-oxymethyl)pyridine and l,2-bis(2-aminophenoxy)ethane or l,3-bis(2-aminophenoxy)propane, respectively, in the presence of the appropriate metal salt as a template agent. In the absence of the metal salt the macrocycles are not formed. The diamine macrocycles L3 and L4 are also formed by reaction of the corresponding diamine and dicarbonyl precursors followed by an in situ reduction with NaBH4. Their complexation potential towards Ln(III) ions were also investigated.
