A comparative investigation on the surface and physicochemical properties of organobimetallic thiocyanate complexes of Cadmium, Zinc, Mercury and Manganese

The single crystals of bimetallic thiocyanate ligands, namely manganese cadmium thiocyanate (MCTC), zinc cadmium thiocyanate (ZCTC), manganese mercury thiocyanate dimethylsulphoxide (MMTD), and cadmium mercury thiocyanate dimethylsulphoxide (CMTD), are cultivated through the utilization of slow solvent evaporation and gradual cooling methodologies. Through the utilization of optical microscopic techniques such as field emission scanning electron microscopy (FESEM), atomic force microscopy (AFM), and epifluorescence, a state-of-the-art methodology extensively employed in the realms of biochemical, medical, and chemical research, we delve into the examination of growth mechanisms and surface topographies. It is additionally employed in LED, fluorescent, and various other luminous sources. The FESEM analysis of MCTC elucidates the manifestation of an extended dendritic growth pattern, which arises from the oscillation of the Mn and Cd metal ligands when connected by thiocyanate (SCN) bridges. The presence of three notable mounds exhibiting cavities within the multi-component thin film coating (MCTC) has been duly ascertained through the utilization of atomic force microscopy (AFM) imagery. The analysis of the histogram unveiled that the average diameter exhibited an augmentation concomitant with the alteration in the breadth of the distribution throughout the process of growth.
