Preparation and Characterization of Nickel Complex [Ni(1-MeIm)6(BF4)2] in Ionic Liquid

Abstract

Nickel complex [Ni(1-MeIm)6(BF4)2, 1-MeIm = 1-methylimidazole] has been prepared in 1-butyl-3-methylimidazolium tetrafluoroborate ([bmim]BF4) ionic liquid by a simple solution phase method. The complex was characterized by elemental analysis, X-ray diffraction (XRD), scanning electron microscopy (SEM), infrared absorption spectroscopy (IR) and thermal analysis. SEM image indicates that the complex is irregular platelets with an uneven thickness in nanometer scale and variable transverse and longitudinal size, from 0.6 to 4 μm.
