Abstract

Copper(II) 4-fluorobenzoate (CFB), prepared from copper(II) acetate monohydrate and 4-fluorobenzoic acid, is a blue powder. Fourier Transform Infrared spectrum of CFB, recorded as potassium bromide disc, indicates the presence of all bonds and functional groups expected of it. The x-ray diffraction pattern indicates that CFB is polycrystalline. The highest diffraction peak occurs at interplanar distance of 15.2 Å which corresponds to particle size of 450A. Scanning Electron Microscopy of CFB shows that it has layered structure. The conductivity of CFB at room temperature is 1.79×10 -11 Scm -1. The value decreases as temperature increases in the temperature "range 30-350K, indicating metallic behaviour. The conduction mechanism obeys Mott's variable range hopping (VRH) model in the temperature range 140-350K. The density of states at Fermi level based on VRH model is 2.91×l0 26eV -1 cm -3. The hopping distance, hopping energy and density of charge carriers at 300K are 0.73Å, 0.002eV and 7.53×10 24cm -3 respectively.
