IrTe$_2$ undergoes a series of charge-ordered phase transitions below roomtemperature that are characterized by the formation of stripes of Ir dimers ofdifferent periodicities. Full hemispherical X-ray photoelectron diffraction(XPD) experiments have been performed to investigate the atomic positionchanges undergone near the surface of $1T-$IrTe$_2$ in the first-order phasetransition, from the $(1\times1)$ phase to the $(5\times1)$ phase. Comparisonbetween experiment and simulation allows us to identify the consequence of thedimerization on the Ir atoms local environment. We report that XPD permits tounveil the break of symmetry of IrTe$_2$ trigonal to a monoclonic unit cell andconfirm the occurence of the $(5\times1)$ reconstruction within the first fewlayers below the surface with a staircase-like stacking of dimers.
