SYNTHESIS AND CHARACTERIZATION OF SOME 10-, 12- AND 14- MEMBERED MACROCYCLIC LIGAND COMPLEXES OF NICKEL (II)

摘要

The template condensation between 1,1,2,2-tetrachloroethane or carbon tetrachloride and 1,2-diaminoethane or 1,3-diaminopropane in the presence of nickel (II) ion are described. The formulation of the synthesized four new macrocyclic products as (1,4,6,9-tetraaza-5,5,10,10-tetrachlorocyclodecane) aquachloronickel (II) chloride ((Ni(TTCD)(H_2O)_2)Cl_2), (1,4,7,10-tetraaza-5,6,11,-12-tetrachlorocyclododecane)diaquanickel(II) chloride ((Ni(TTCD)(H_2O)_2)Cl_2), (1,5,7,11-tetraaza-6,6,12,12-tetrachlorocyclododecane)diaquanickel(II) chloride ((Ni(TTDE)(H_2O)_2)-Cl_2) and (1,5,8, 12-tetraaza-6,7,13,14-tetrachlorocycloteradecane)diaquanickel(II) chloride ((Ni(TTTE)(H_2O)_2)Cl_2) has been supported by elemental analyses, conductivity measurements, melting points and spectroscopic studies.
