Growth of bis(thiourea) cadmium chloride single crystals - a potential NLOmaterial of organometallic complex

Growth aspects of bis(thiourea) cadmium chloride (BTCC) single crystals has been investigated. The crystals were grown from aqueous solution by slow c ooling technique. The effect of pH on the growth rate and morphology has be en discussed. The results indicated that as the pH of the solution is decre ased the growth rate along the a-direction, R[1 0 0] increased and at a pH below 1, the morphology of the crystals changes from hexagonal to rectangul ar. Single crystal X-ray diffraction studies confirm the structure. Fourier transform infrared analysis and single crystal X-ray diffraction analysis confirms the presence of sulfur to cadmium bonds in the complex. (C) 2000 E lsevier Science B.V. All rights reserved.
