摘要：

The free Schiff base macrocycles containing pendant groups have been synthesized by the condensation reactions of N,N-diphenylsuccinamide/adipamide, N,Ndipyridylsuccinamide/ adipamide with ethylenediamine. The reactions of these ligands with lanthanum(III)/praseodymium(III) chlorides have been carried out in ethanol and macrocyclic complexes of type [LnCl(3)(mac)] have been isolated. Tentative structures of the complexes have been proposed on the basis of elemental analyses, electrical conductance, magnetic moment and spectral (IR, electronic, H-1 NMR) data. The metal ions have seven-coordinated geometry.
