The structural stability of Mn3Zn0.8Ni0.2N was investigated up to 29.9 GPa by in situ angle dispersive X-ray diffraction using synchrotron radiation source and a diamond anvil cell. No structural phase transition was observed in the pressure range of 0-29.9 GPa. This result indicates that the changes in the physical properties of Mn3Zn0.8Ni0.2N under pressure are not induced by structural phase transition. Through fitting the Birch-Murnaghan equation, we obtain the bulk modulus B0=86.5 GPa for Mn3Zn0.8Ni0.2N, assuming its first order derivative at ambient pressure.
