Synthesis, Structure, and Non-Linear Optical Properties of New Metal Semi-Organic Complex: 1,4-diazabicyclo[2.2.2]octane-1,4-diium tris(nitrato)-silver

Optically transparent metal semi organic single crystal of 1,4-diazabicyclo[2.2.2]octane-1,4-diium tris(nitrato)-silver (DTNS) is synthesized using slow evaporation solution technique. This single crystal is grown with dimension up to 3x0.6x0.2cm3$3 \times 0.6 \times 0.2 \,\,{\rm{cm<^>3}}$ using 1,4-diazabicyclo[2.2.2]octane (DABCO) as solute and water and methanol as solvent in the presence metal salt silver nitrate. Single crystal X-ray diffraction (XRD) study showed a trigonal structure with space group P3c1 and the sum formula C6H14AgN5O9$C_6 H_{14} Ag N_5 O_9$. The composition of metal Silver (Ag) in single crystal is confirmed through Energy Dispersive X-Ray Analysis. The confirmation of various functional groups in DTNS molecular structure is characterized by Fourier Transform Infrared Spectroscopy (FT-IR). UV-Visible absorption study showed the cut-off wavelength at 250 nm with transparency 350-700 nm and the bandgap is about 3.3 eV. The thermal stability and melting point temperature is analyzed by Thermogravimetry-Differential Scanning Calorimetry (TG/DSC). The third order Non Linear Optics (NLO) efficiency of the synthesized crystal is 2x106$2 \times 10<^>6$ times greater than that of KDP. All of these analysis implies that DTNS crystal can be beneficial element for non-linear optical applications.
