Synthesis growth and characterization of some novel semiorganic crystals

Abstract

Single crystals play an important role in todays technological systems in the fields of communication transportation medical energy information etc Safety technologies depend critically on the availability of suitable single crystals with tailored properties Due to potential applications of single crystals in modern advancing technology several research works are being carried out to prepare grow and characterize new crystals So crystal growth and characterization has become an important area of research Metal organic framework MOF crystals have received much attention of researchers due to their fascinating structures and potential applications Metal succinates are the salts of succinic acid with each of the four terminal carbonyl oxygen atoms in the succinate ligand forming coordinate bonds with the central metal ion The interesting aspect of these material crystals is in the number of water molecules present and consequently the variation in the crystal structure producing variation in the number of hydrogen bonds in the crystal. The present thesis work involves the growth and characterization of eleven single crystals viz pure calcium succinate CS pure barium succinate BS mixed barium calcium succinate BCS with five different ratios BCS 28 BCS 46 BCS 55 BCS 64 and BCS 82 glycine doped calcium and barium succinates GCS and GBS and urea doped calcium and barium succinates UCS and UBS All the eleven crystals were grown by using the simple slow evaporation of solvent method at room temperature newline
