Description
Summary:Diaquasuccinatocadmium(II) has been studied by single-crystal X-ray diffraction and FTIR and Raman spectroscopies at room temperature. The structure consists of seven-coordinated Cd atoms bridged by succinate ions to form two-dimensional polymers perpendicular to the b axis. Hydrogen bonds embracing one of the coordination water molecule and a carboxylate residue stabilize the three-dimensional structure. The spectroscopic data are consistent with the structural model. Thermal dehydration and decomposition processes have been also investigated using TG–DTA measurements, FTIR spectroscopy, and powder X-ray diffraction analysis. A phase transition of the amorphous anhydrous compound to a stable crystalline phase was observed at 262°C.
