Preparation of Some Complexes of Nickel (II) and Copper (II) Metals with Macrocyclic Ligand, 1,7,10,16- tetraaza-8, 9, 17, 18-dibenzo - 3,4,5,12,13,14 -Difuranyl Cyclo Octadeca - 1, 6, 10, 15-Tetraene

Abstract

The complexes of Nicke l(II) and Copper(II) salts have been prepared with the macrocyclic ligand-1,7,10,16-tetraaza-8, 9, 17, 18-di benzo - 3,4,5,12,13,14-difuranylcyclooctadeca- 1, 6, 10, 15-tetraene. On the basis of characterization of compledxes formed with the macrocyclic ligand by usual physico-chemical methods such as elemental analysis, mea- surement of electrical conductance, magnetic moment and electronic tran- sition spectra of the complexes and I.R. spectral behaviour of both the ligand and the complexes. All the complexes of both the metals have been found to be non-electrolyte, mono-meric, paramagnetic with octahedral geometryy . The general molecular formula of the complexes have been found to be [M(L) (X)2] Where M= Nickel(II) and Copper(II) Cations, L= macrocyclic ligand and X= monodentate anion.
