High-pressure angle dispersive X-ray diffraction measurements up to 23·6 GPa have been carried out on the ductile intermetallic compound, ErCu. Our measurements show that the ambient CsCl structure (SG: Pm-3m) is stable up to the highest pressure of the present measurements. A second-order Birch-Murnaghan equation of state fit to the pressure, volume data yielded a bulk modulus of 67·6 GPa with the pressure derivative of bulk modulus fixed at 4.
