Abstract A new copper (II) sodium (I) tartrate trihydrate with general formula of [(Na2 Cu2 (C4H4O6) 3 (H2O) 3) 3H2O] (NaCuT) was synthesized and grown from the silica gel. The monoclinic structure and the space group P21 of the as-grown crystal are calculated and non identical with copper tartrate is found by the single crystal and powder X-ray diffraction studies. The presence of O H, C O, C O, C H and M O bonds were confirmed by Raman FTIR spectroscopy. The UV spectrum showed the transmittance in the Ultra-Violet region about the lower cutoff wavelength at 310.5 nm which makes the material to be suitable for UV filters. Different decomposition stages with respect to the mass loss of the copper sodium tartrate were studied by thermo gravimetric analysis. Occurrence of the improved electrical conductivity by the pi electrons of the C O and O-H----O groups of the CuNaT crystal was established by the dielectric studies. From Z-scan studies, the present sample proved its suitability for non linear optical applications.
