Investigation on the crystal growth and characterisation of an organometallic non linear optical crystal - Tetrathiourea mercury tetrathiocyanato manganate

► Optimization of solvent, pH and temperature was carried out. ► Good transparent single crystal of TMTM of dimension 2.7 cm × 0.5 cm × 0.4 cm was grown. ► The layer growth pattern reveals the 2D growth mechanism. ► The stiffness constant shows that the bond strength in the complex is good.
