A new series of alkaline-earth and transition metal complexes of Ca(II), Sr(II), Ba(II), Co(II), Ni(II) and Cu(II) with two pendant-arm oxaaza macrocyclic ligands, L1 and L2, with N4O2 and N4O3 donor sets, respectively, were synthesized by reaction of the ligand and the appropriate perchlorate salt in refluxing acetonitrile. The reactions gave analytically pure products that were characterized by...
The coordination capability of the pendant-arm macrocyclic ligands – with different sizes, nature and number of the donor atoms – dioxotriaza 17-membered (L 1 ) and pentaaza 17-membered (L 2 ) towards nitrate and perchlorate Cd(II) salts, has been investigated. The complexes were prepared in 1:1 metal/ligand molar ratio. The characterization carried out by elemental analysis, FAB mass...
