Investigation of novel organometallic and physicochemical properties of [Sr (C10H20O5)2·Co (SCN)4]: SCCTC single crystal for NLO application

A novel inorganic polymers and organic spacers (IPOS) derivative strontium cobalt chloride bis 15-crown-5-ether tetra ammonium thiocyanate (SCCTC) single crystal synthesis via solution growth technique. Initially, the detailed crystallography information of cell parameters and data structure were carried out by single crystal X-ray diffraction studies, which reveal that the orthorhombic system acquires centrosymmetric space group of Pnma . As-grown crystal chemical bonding assignments, elemental compositions confirmed by using energy dispersive X-ray and vibrational spectroscopy. Additionally, H-bond present in the prepared sample identified by CHNS analysis. In this work, the cut-off wavelength was found at 353 nm with band gap (Tauc’s plot) of 3.22 eV can be ascertained from the UV–Visible-NIR spectrum. The prominent crystal growth mechanism were examined by using scanning electron microscope, chemical etching study to correlate the surface texture and reverse growth rate etch pattern. For device fabrication, lattice dynamics, thermal and mechanical properties are necessary for testing the sample assessment by thermogravimetric, Vickers hardness and dielectric measurement. Using single beam Z-scan technique under 633 nm excitation were carried out experimentally non-linear susceptibility, absorption coefficient and refractive index. The above results suggest that grown crystals have good transmittance, moderate thermal, mechanical and large susceptibility values. So, these properties turn into be potential materials for making optical device applications.
