Abstract
Some nickel(II) complexes of 1,10-phenanthroline and 2,2′-bipyridine, associated with counterions such as Cl−, NO3−, OAc−, and SO42− have been synthesized and characterized by elemental analysis, conductance, spectral measurements, and antimicrobial studies. The conductance measurement indicates that [Ni(bipy)2H2O(NO3)](NO3), [Ni(phen)2(H2O)Cl]Cl·3H2O·CH3OH and [Ni(phen)3](NO3)2.4H2O are 1:1 and 1:2 electrolytes, respectively. The infrared and electronic spectral studies are consistent with the adoption of probable six-coordinate octahedral geometry for the complexes. The microbiostatic activity revealed that all the complexes showed pronounced activity against the tested fungi but little or no antibacterial activity. A six-coordinate octahedral geometry was established for [Ni(phen)2(H2O)Cl]Cl·3H2O·CH3OH using X-ray crystallography.
