Thermal, UV and FTIR spectral studies of urea-thiourea zinc chloride single crystal

A single crystal of urea-thiourea was grown by slow evaporation of aqueous solution at room temperature. The bright and transparent crystals obtained were characterised by TG-DTA, UV and FTIR spectral analyses. A fitting decomposition pattern for the title compound was formulated on the TG curve which shows a two stage mass loss between 200 and 750 A degrees C. DTA curve shows exothermic peaks supporting the formulated decomposition pattern in this temperature range. The UV and FTIR spectra show the characteristic absorption, vibration frequencies due to urea-thiourea zinc chloride crystals. Detailed structural analysis of the compound is under progress.
