Energy dispersive X-ray diffraction experiments on NdBr(3) have shown a possible distortion of the known PuBr(3)-type orthorhombic structure at high pressure but not the formation of a new crystal structure, as had been suggested from earlier work based on analysis of absorption and phonon Raman spectra. The bulk modulus B(0) and its pressure derivative B(0)' were calculated from the compression curve to 20 GPa to be about 17 +/- 1 GPa and 8.7 +/- 2 respectively.
