Four novel Knoevenagel type Cu(II), Ni(II), Co(II) and Zn(II) macrocyclic complexes derived from 3-cinnamalideneacetoacetanilide and N-(2-aminoethyl)-1,3-propanediamine have been synthesized. The nature of complexes and the geometry have been inferred from their microanalytical data, magnetic susceptibility measurements, IR, UV-Vis., 1H NMR, ESR and mass spectral techniques. The low electrical conductance...
