    Abstract: Study mass attenuation coefficient of new chemical compound C<sub>28</sub>H<sub>24</sub>N<sub>6</sub>O<sub>6</sub>Cu by using gamma ray radiation (&gamma;), emitted from deferent sources Co<sup>57</sup>, Ba<sup>133</sup>, Na<sup>22 </sup>, Cs<sup>137</sup>, Mn<sup>54</sup> and Co<sup>60</sup> with energies from 122-1330 keV. The compound was subjected to gamma radiation and detector density of radiation that across the sample, used scintillation NaI(Tl) detector with resolution 8.2% (at 662 keV) to detector beam of gamma ray. The attenuation coefficient data has used to obtain the effective atomic numbers (Z<sub>eff</sub>) and effective electron densities (N<sub>eff</sub>), atomic cross-section (&#1073;<sub>t</sub>) and electronic cross-section (&#1073;<sub>e</sub>) of dinitratobis. It was observed that the effective atomic number (Z<sub>eff</sub>) and effective electron densities (N<sub>eff</sub>) initially decrease and tend to be almost constant as a function of gamma-ray energy. Z<sub>eff </sub>and N<sub>eff</sub> experimental values showed good agreement with the theoretical value which took from XCOM program of Hubbell J.H.for the individual elements.
