Raman and x-ray diffraction measurements have been performed on Co substituted YBa2Cu3-xCoxO6+8. The x-ray diffraction data show that the structure transforms from orthorhombic to tetragonal at x=0.13. The features in the Raman spectra change smoothly throughout the investigated concentration range
