摘要
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)(2)H2O(NO3)](NO3), [Ni(phen)(2)(H2O)Cl]Cl center dot 3H(2)O center dot CH3OH and [Ni(phen)(3)](NO3)(2).4H(2)O 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 center dot 3H(2)O center dot CH3OH using X-ray crystallography.
