Novel silver co-ordianted thiourea adducts was synthesized by mechanochemical stirring process. Structural data of TuAgN (1:1) and TuAgN (4:1) were collected with the help of single crystal X-ray diffractometer and their unique structural properties were studied and compared. The ratio of the compounds 1:1 and 4:1 represents the mole ratio of thiourea and silver nitrate which has taken for the synthesis. i.e. TuAgN (1:1) indicates, 1 mole of thiourea and 1 mole of silver nitrate and TuAgN (4:1) reveals, 4 mole of thiourea and 1 mole of silver nitrate. The crystalline materials belong to Triclinic and Tetragonal systems with a space group of P-1 and I4(1) respectively. In both the crystal systems, a single Ag atom coordinate with three thiourea ligands and the chain is continued through Ag to Ag interactions. TG/DTA study provides the details of thermal stability and thermal decomposition behavior of the crystals. Electrical characterizations like dielectric constant, dielectric loss and their importance were studied at different temperatures (40, 60 and 80 degrees C) in the frequency range from 50 Hz to 5 MHz.
