Spectroscopic and Thermal Studies of Gel-Grown Copper Malonate Crystals

Abstract

Copper malonate crystals were grown using silica gel as the growth medium. The grown crystals were characterized by X-ray diffraction analysis (XRD), Fourier transform infrared spectroscopy (FTIR) and Fourier transform Raman spectroscopy (FT Raman). The thermal decomposition of the compound was investigated using thermogravimetry (TG) and derivative thermogravimetry (DTG) measurements.

Structural, thermal and electrical characterization on gel grown copper succinate dihydrate single crystals

“…The differential scanning calorimetry analysis was done with a heat flow from 50 to 375 • C at the rate of 10 • C min −1 . The thermograms of copper succinate crystals show two endothermic peaks as shown in figure 6, one at 90 • C corresponding to the loss of water molecules and a second peak at 339 • C associated with the complete dehydration of the crystal and then phase transition of the anhydrous succinate to cuprous oxide [11].…”

“…The introduction of transition metals in the framework has increased the range of possible applications by exploiting their electronic and magnetic properties [5][6]. A great deal of work has been reported on the growth and property studies of metal-organic frameworks of transition metals with dicarboxylic acids such as tartaric, oxalic and malonic acids [7][8][9][10][11][12]. Succinic acid is an organic dicarboxylic acid and each of the four terminal carboxyl oxygens in the succinate ligand can form coordinate bonds with the central metal ion [13].…”
