The spectroscopic investigation of the solid solutions GdCr3(BO3)4 (sp.gr. R32) – NdCr3(BO3)4 (sp.gr. С2/с) is presented. The single crystals NdxGd1−xCr3(BO3)4, 0≤x≤1 with the step of 0.1, were grown by a flux method. Crystal structures were identified by terahertz and optical spectroscopy methods. Ab initio calculations in the frame of density functional theory allowed us to separate modes belonging to the R32 and С2/с phases and to estimate the ratio of these phases in NdxGd1−xCr3(BO3)4 crystals. Content of the monoclinic phase (C2/c) increases with growth of the Nd concentration.
