“…The thermal decomposition of CA and MA complexes takes place in two major stages: (i) dehydration of the hydrated complexes to form unhydrated intermediates (45-140 1C); (ii) decomposition of the unhydrated intermediates to form metal oxides (250-350 1C). 23,24 The weight loss in the first stage corresponds to the departure of H 2 O molecules either coordinating to the metal cores or present in the complexes via H bonds. The weight loss in the second stage is primarily due to the decomposition of the unhydrated complexes to form metal oxides by losing H 2 O, CO or CO 2 molecules.…”

“…The metal organic crystals are found to possess potential applications in catalysis, luminescence, gas adsorption and separation (Tanmoy Maity et al 2012). Extensive study on the crystallization and properties of metal dicarboxilates such as oxalates, tartrates and malonates are made by many investigators (Sahaya Shajan and Mahadevan 2004;Basharat Want et al 2007;Quasim et al 2009Quasim et al , 2010. However, studies on systematic growth and properties of metal succinates are very few in literature.…”

Single crystals of barium succinate (BaC 4 H 4 O 4) were grown in silica gel medium using controlled chemical reaction method. Plate-like single crystals of size up to 3 × 2 × 0⋅2 mm 3 was obtained. Single crystal X-ray diffraction (XRD) studies confirmed that structure of the title compound is tetragonal. Powder X-ray diffraction (PXRD) pattern of the grown crystal and the Fourier transform infrared (FT-IR) spectrum in the range 400-4000 cm-1 are recorded. The vibrational bands corresponding to different functional groups are assigned. Thermal stability of the grown crystals is confirmed by differential scanning calorimetry (DSC). Dielectric constant and dielectric loss have been calculated and discussed as a function of frequency at different temperatures.

“…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].…”

Copper succinate dihydrate (CuC 4 H 4 O 4 • 2H 2 O) crystals were grown by controlled diffusion in silica gel medium and long thin plate-like single crystals of length up to 5 mm were obtained. The single-crystal x-ray diffraction studies showed that it crystallizes in the triclinic space group P1(2), with a = 6.419, b = 7.622, c = 8.076 Å, α = 76.25 • , β = 73.61 • and γ = 81.30 • . Raman and infrared spectra of the grown crystals were recorded in the 50-3500 and 400-4000 cm −1 frequency regions, respectively. The different vibrational modes of the title compound were assigned and discussed. The optical band gap of the material was determined by UV-visible spectroscopy. The thermal stability of the grown crystal was studied by thermogravimetric-differential thermogravimetric and differential thermal calorimetric analysis. Surface feature studies on the grown crystals were carried out by optical microscopy, scanning electron microscopy and atomic force microscopy. The electrical characterization on the grown crystals was also done and the variations of dielectric constant and ac conductivity with frequency of the applied field were discussed.
