The XRD analysis shows that the orthorhombic structure is maintained to a maximum pressure of 44.5 GPa. The XRD data show that the bulk modulus is K0=292 (18) GPa with K0'=3.25(0.85). In addition, the high-pressure compression behavior of Cr3C2 is studied by first principles calculations. The obtained bulk modulus of Cr3C2 is 323 (1) GPa.
