Abstract
Raman microprobe and diffuse-reflectance Fourier transform IR spectra of a series of seven metal hexaborides show that the basic cubic symme try of these systems is lowered owing to lattice vacancies. The result ing wave vector is oriented along the C4 axis of the first Brillouin z one. Studies of enriched boron samples indicate that the vacancies in the B-6 structure are located at boron sites.
