Template Synthesis of 16-membered Octaazamacrocyclic Complexes of Zn(II) Ions
Keywords:
Octaazamacrocyclic ligand, template synthesis, Zn(II)Abstract
Template condensation of metal ion with hydrazine, 2,4-Pentanedione and acetaldehyde in a 1:4:2:2 molar ratio resulted in the formation of 16-membered octaazamacrocyclic complexes: dichloro/nitro[2,5,8,10,13,16-hexamethyl-3,4,6,7,11,12,14,15-octaazacyclohexadecane - 2, 7, 10, 15- tetraene)Zn(II). The formula of the complex was derived and found to be of the type [ZnLX2] where X=Cl or NO3. The geometry of the complexes has been characterized by elemental analysis IR measurements. An octahedral geometry is suggested for the complexes.
