Abstract Single crystal of oxalato-bridged, Cesium-extended frame work, Cesium Hydrogen Oxalate Dihydrate (CHOD), has been synthesized by slow evaporation solution growth technique. Diffraction studies were used to identify the geometry of the atoms present in the primitive cell of the crystal. The title compound has crystallized in triclinic category-bearing space group P-1. Spectroscopic investigation of the compound was done by FTIR and FT-Raman techniques. From UV–Vis studies, optical absorption edge was ascertained as 241 nm. It has excellent optical transmission window throughout the visible region. Energy dispersive X-ray analysis (EDAX) affirms the presence of Cesium in the compound. Fluorescence decay of the molecules present in the excited state for the crystal was studied. Hirshfield surface maps intermolecular contacts present in the crystal and the contributions made by the contacts were assessed by 2D Finger print plots. Z-Scan studies ascertain the magnitude of nonlinear refractive index and nonlinear refraction.
1 Introduction Metal Organic frameworks (MOF) are porous, crystalline and robust hybrid materials of organic and inorganic constituents with inconceivable tunability of geometry, size and chemical nature. Tunability of MOFs can be made without change in their underlying topology [1,2]. It consists of
ordered, crystalline and extended array of charge compensating metal ions coordinated to organic linkers. MOFs are known for astounding void fraction i.e. only 10% area of the material is occupied and it has expansive interior region without occupation of molecules and large void space. Their high porosity leads MOFs to be used in energy storage devices. They are used in batteries and superconductors.
