<description xml:lang='en' descriptionType='Abstract'><p>A<sup>II</sup>B<sub>2</sub><sup>III</sup>C<sub>4</sub><sup>VI</sup>&nbsp;defect chalcopyrites (DC) and spinels were investigated by Raman scattering spectroscopy under hydrostatic pressure up to 20 GPa. All these compounds were found to undergo a phase transition to a Raman inactive defect NaCl-type structure. The phase transition is reversible for spinels and irreversible for DC. From the analysis of the pressure behavior of Raman-active modes, it was concluded that the phase transition from spinel to NaCl-type structure is direct in MnIn<sub>2</sub>S<sub>4</sub>&nbsp;and CdIn<sub>2</sub>S<sub>4</sub>, while it occurs via an intermediate LiVO<sub>2</sub>-type NaCl superstructure in MgIn<sub>2</sub>S<sub>4</sub>. The observed differences in the pressures and the paths of the pressure-induced phase transitions in A<sup>II</sup>B&nbsp;<sub>2</sub><sup>III</sup>C<sub>4</sub><sup>VI</sup>&nbsp;compounds are discussed.</p></description>
