Abstract
The coordination compounds of Cr(III), Mn(II) and Co(II) metal ions derived from quinquedentate 2,6-diacetylpyridine derivative have been synthesized and characterized by using the various physicochemical studies like stoichiometric, molar conductivity and magnetic, and spectral techniques like IR, NMR, mass, UV and EPR. The general stoichiometries of the complexes are found to be [Cr(H(2)L)X] and [M(HL)X], where M=Mn(II) and Co(II); H(2)L=dideprotonated ligand, HL=monodeprotonated ligand and X=NO(3)(-), Cl(-) and OAc(-). The studies reveal that the complexes possess monomeric compositions with six coordinated octahedral geometry (Cr(III) and Mn(II) complexes) and six coordinated tetragonal geometry (Co(II) complexes).
