The crystal structure and vibrational spectra of cation-deficient nanostructured zinс ferrite Zn&sub(0.34)Fe&sub(2.53)☐&sub(0.13)O&sub(4) (where ☐ denotes the cation vacancies) have been studied using X-ray diffraction and Raman spectroscopy methods in the pressure range of 0–34 GPa. Our results indicate a phase transition from the initial cubic phase with space group Fd 3^- m to a high-pressure phase with orthorhombic symmetry of Bbmm at pressures above 18 GPa. This phase transition is accompanied by changes in lattice parameters, unit cell volume, interatomic bond lengths, and vibration mode frequencies.
