Studies on novel single crystals of tri-nitrophenol methyl p-hydroxybenzoate

Good quality single crystal of tri-nitrophenol methyl p-hydroxybenzoate (TNMPHB) has been successfully grown from aqueous solution by a slow evaporation technique. Single-crystal X-ray diffraction analysis confirms that the crystal formed by crystallizing in triclinic system with space group P1¯ is of a new kind. The functional groups of the compound are confirmed qualitatively by FT-IR spectral analysis. An optical absorption study on this sample reveals the minimum absorption region is well suited for optical applications. Thermal analysis carried out on the compound reveals that the sample is stable up to 187 °C.
