SYNTHESIS AND SPECTRA STUDIES ON CHROMIUM COPPER AND CADMIUM COMPLEXES OF (TETRAMETHYLDIBENZOTETRA AZA {16}ANNULENE [L])

In high dilution method and in ethanol solution has been reacted two moles (o – phenylendiamin ) with tow moles (2,5 – Hexandion) to yield Macrocyelic Ligand type N4 . This Ligand ( L ) has been reacted with some metal ion to product metal complexes (M L ) where M = Cr+3, Cu+2and Cd+2. The metal complexes were characterized by elemental analysis, (C.H.N), molar conductivities, I.R spectra, UV-Vis., HPLC, and atomic absorption. From the above data the proposed molecular structure for (ML) is octahedral, and Trigonal bipyrimed
