  Compressibility of boron subarsenide B12As2 has been studied by synchrotron
X-ray diffraction up to 47 GPa at room temperature in a diamond anvil cell
using Ne pressure transmitting medium. A fit of experimental p-V data by Vinet
equation of state yielded the bulk modulus of 150(4) GPa and its first pressure
derivative of 6.4(3). No pressure-induced phase transitions have been observed.
