Abstract

Growth of Cobalt Malonate (CoC3H2O4 .2H2O) crystals by controlled ionic diffusion of reactants through hydro silica gel is accomplished and the conditions conducive for the growth are optimized. The X-Ray Diffraction (XRD) pattern of the sample reveals the crystalline nature. The FTIR and FT Raman spectra of the Cobalt Malonate crystals are recorded and the vibrational assignments have been made with possible explanations. From Diffuse Reflectance Spectroscopy (DRS) studies, the band gap of the material is also determined.
