Synthesis, growth, spectral, optical and thermal studies of thiourea family crystal: TTPB

In the present work, bulk size single crystal of tetrakis thiourea potassium bromide [K(N 2 H 4 CS) 4 Br]; (TTPB) has been grown from an aqueous solution using slow evaporation solution growth method. The XRD result proved that the compound crystallize in tetragonal crystal system with space group P4 1 . The FT-IR spectrum of TTPB has clearly identified the functional groups of thiourea in the resulting compound. The TG-DTA and DSC studies have been carried out on the grown sample of TTPB and the results are reported. The etching and scanning electron microscope studies were also carried out to understand the growth pattern and surface morphology of TTPB. The spectral, optical and thermal studies of TTPB are compared with the similar thiourea complex crystal [K(N 2 H 4 CS) 4 I]; (TTPI) and reported.
