The temperature dependence of the magnetic susceptibility and the reflectance spectrum of the purple compound Co/sub 2/SiO/sub 4/ sre reported. Although the color of the compound might suggest the presence of tetrahedrally coordinated Co(II) ions, it is shown that the magnetic data and the details of the spectrum lead unambiguously to the conclusion that the Co(II) ions are octahedrally coordinated. This is in sgreement with the previously reported x- ray powder pattern which indicated that Co/sub 2/SiO/sub 4/ has the olivine rather than the phenacite (Willemite) structure. (auth)
