New macrocyclic ligands were prepared and chromium(III) stability in the marcrocyclic cavities are reported. Two of them have four-coordinate [N2O2]:[N4], third one has five-coordinate [N2O2S] and the last one has six-coordinate [N4O2] donor macrocyclic cavities. These macrocyclic ligands have been synthesized with their chromium(III) complexes which have mononuclear nature and their structural features

) Complex with Lariat Tetraazacrown Ether as Ligand
Four o-toluic acid pendant groups have been attached to a tetraaza crown ether to prepare the novel tetraazamacrocyclic ligand H4L, 4,7,13,16-tetrakis(2-carboxybenzyl)-1,10-dioxa-4,7,13,16-tetraazacyclooctadecane. The trinuclear copper(II) complex of the ligand, [Cu3L·2H2O]2+·2NO3−·2H2O, has been newly synthesized, and its subsequent structuralcharacterization has revealed that it consists of three
