We consider an entangled Ising-XY Z diamond chain structure. Quantum correlations for this model are investigated by using quantum discord and trace distance discord. Quantum correlations are obtained for diferent values of the anisotropy parameter, magnetic ield and temperature. By comparison between quantum correlations, we show that the trace distance discord is always larger than quantum discord. Finally, some novel efects such as increasing the quantum correlations with temperature and constructive role of anisotropy parameter, which may play to the quantum correlations, are observed.
