Synthesis And Spectral Of Some Biologically Active Chromium (III) Complexes With Macrocyclic Ligands
Abstract: A large number of modern techniques have been developed for the synthesis of macrocyclic complexes. Forty chromium complexes of the type [CrX2.L1-20]X; (Where X=Cl or NO3; L=macrocyclic ligands) derived from condensation of 2,3-butanedione or 1, 2-diphenyl-ethane 1,2-dione (2mmol) with different aliphatic diamines (2mmol) have been synthesized and characterized by elemental analysis, molar conductivity, electronic spectra, IR spectra, magnetic moment and X-ray photoelectron data (i.e. XPS data). An octahedral geometry is …

Synthesis and Spectroscopic Studies of 12-Membered Macrocyclic Transition Metal Complexes with Tetradentate Ligand
Abstract: Tetra-aza macrocyclic transition metals complexes of type: [M(C12H4N8)X2]; where, M = Co (II), Ni(II), Cu(II), Zn(II); X= Cl-1 , NO3 - , CH3COOhave been synthesized and characterized. On the basis of conductance data; elemental analyses, the character of the complexes have been suggest and it was found that all the complexes have 1:2:2 stoichiometry and are nonelectrolytic in nature. Tentative geometry of the new synthesized macrocyclic complexes had been proposed …
