| Abstract: | New double-ring octa-aza macrocyclic complexes, synthesized by condensation of oxamide-N,N-diethanoic acid with diethylenetriamine in 1:2 ratio in the presence of CuII, NiII or CoII, have been characterized by elemental analyses, i.r., u.v., magnetic susceptibility and conductivity measurements. The complexes are non-electrolytes, in which each metal ion is in a spin-free state in a pseudo- octahedral geometry. The high magnetic moments are attributed to a ferromagnetic effect. |
