Effect of Samarium Coordination on the Structural, Thermal and Optical Properties of Salicylic Acid Single Crystal
Role of materials as a single crystal is invaluable not only for device application point of view but also for scientific investigations. Rare earth coordinated with salicylic acid has been grown in the form of single crystal because these crystals have tremendous application in optical devices. Samarium coordinated with salicylic acid was successfully grown as a single crystal by low temperature solution technique using mixed solvent of methanol and water in equal ratio. Structural characterization was carried out by single crystal X-ray diffraction analysis and it crystallizes in centrosymmetric space group P121/c1 with lattice parameters a = 4.9149 Å, b = 11.1937 Å, c = 11.5301 Å and α = 90°, β = 89.271°, γ = 90°. Thermal stability of the crystal was analyzed by thermo gravimetric / differential thermo analytical (TG/DTA) studies. UV—Vis—NIR study suggests that the crystal is highly transparent in the visible region.
