Crystal growth, structure and characterization of o-hydroxybenzoic acid single crystals: Solvent effects

Single crystals of o -hydroxybenzoic acid ( o -HBA, salicylic acid) have been grown by slow evaporation solution growth technique. It crystallizes in monoclinic system with two molecular units in the cell (centrosymmetric space group P 2 1 /c). The lattice parameters are a  = 4.8967(6) Å, b  = 11.22...

Zusammenfassung:Single crystals of o -hydroxybenzoic acid ( o -HBA, salicylic acid) have been grown by slow evaporation solution growth technique. It crystallizes in monoclinic system with two molecular units in the cell (centrosymmetric space group P 2 1 /c). The lattice parameters are a  = 4.8967(6) Å, b  = 11.2204(14) Å, c  = 11.3027(15) Å and β = 92.096(12)°. The modes of vibrations of different functional groups present were identified by FT-IR studies. Differential scanning calorimetry (DSC) study reveals the purity of the sample and no decomposition is observed up to the melting point. The crystals are further characterized using UV–Vis and powder XRD. Effect of solvents on the growth and morphology has been investigated. The crystalline cohesion is achieved by intra and intermolecular hydrogen bonds.
