In situ high-pressure energy dispersive X-ray diffraction experiment on Zn3N2 has been performed by using a diamond anvil cell instrument with synchrotron radiation at room temperature. The results showed that the structure of Zn3N2 is stable in the experimental pressure range up to 25.2 GPa. According to the Birch-Murnaghan equation of state determined from the relationship of unit cell volume and pressure, assuming B'(0)=4, the bulk modulus B-0=228(2)GPa has been obtained.
