Sodium tetraborate decahydrate single crystals were grown from aqueous solution by slow cooling technique. Nucleation and growth kinetics give valuable information about the crystal growth process, which can be utilized in the growth of large size crystals. Attempt are made to study the nucleation parameters such as solubility, induction period, interfacial tension, Gibbs critical free energy, radius of critical nuclei. The crystal possess positive temperature coefficient of solubility. XRD analysis shows that the crystal crystallizes in monoclinic system with space group C2/c. Thermal stability of the crystal was analyzed by TGA/DTG. From optical studies band gap of the material was found to be 5.64 eV. The existence of SHG was confirmed by Q-switched Nd:YAG laser technique. © 2016 Elsevier B.V.

A metalorganic NaHC2O4·H2O single crystal was successfully grown by slow evaporation method. The grown crystal was exposed to single crystal X-ray diffraction which confirms that the crystal belongs to triclinic crystal system with P1¯ space group having unit cell parameters a = 6.53 Å, b = 6.71 Å, c = 5.72 Å and α = 75°, β = 85.06°, γ = 70.31°. The presence of functional groups, bonding between the organic ligand and the metal atoms were identified through FT-IR spectral studies. The UV–vis–NIR study revealed that the transparency of the grown crystal was about 60% in the entire visible region and the cut-off wavelength was observed at 295 nm. The TG/DTA studies reveal that the metalorganic complex is thermally stable upto 125 °C. The thermodynamic parameters of various decomposition point for different temperatures were also calculated. Vickers microhardness test was carried out on grown crystal to study its mechanical stability. The frequency dependent dielectric constant and dielectric loss were analysed. The electrical relaxation mechanism has been studied using AC conductivity. Another interesting feature of this centrosymmetry sodium hydrogen oxalate hydrate crystal shows an SHG active signal and efficiency is almost equivalent to that of KDP. © 2017 Elsevier B.V.
