Synthesis, antimicrobial activity and molecular modeling of cobalt and nickel complexes containing the bulky ligand: bis[ N-(2,6-diisopropylphenyl)imino] acenaphthene
Two cobalt and two Nickel complexes of bis[ N-(2,6-diisopropylphenyl)imino]acenaphthene ( Pr-BIAN) ligand, have been synthesized. These complexes, namely [Co(Pr-BIAN)Cl 2] 1, [Co(OAc) 2 (Pr-BIAN) 2](ClO 4) 2, [Ni(Pr-BIAN)(NO 3) 2] 3 and [Ni(Pr-BIAN)2](ClO 4) 2 4, were characterized by elemental anal...
