Using a synchrotron radiation source and a diamond anvil cell, we measured the pressure dependence of the lattice parameters of a polycrystalline sample. Up to a pressure of 53 GPa, no phase transformations were observed. As for the isostructural hexagonal the compressibility along the c axis was greater than along a. The bulk modulus is with a pressure derivative of This work shows that the replacement of Si by Ge in results in a systematic decrease in the bulk moduli.
