Room temperature X-ray powder diffraction data were used to investigate modulated crystal structures of two monoclinic polyphosphates of crystal form  C , In(PO 3 ) 3  and Y(PO 3 ) 3 , by the Rietveld refinement. The structures were refined with the program JANA2006 in the superspace groups  Xc (0 β 0)0,  β  = 1/3, for commensurately modulated In(PO 3 ) 3 , and  Cc (0 β 0)0,  β  = 0.36564(7), for incommensurately modulated Y(PO 3 ) 3 . The positional modulations were described with the first-order harmonic functions. The Rietveld refinement was performed with soft restraints on bond lengths and valence angles in PO 4  tetrahedra, as well as on angles in MO 6  octahedra. No initial information about modulation parameters was used. A good agreement of the observed and calculated intensities of main and satellite reflections was achieved for both compounds. Obtained modulated structures of In(PO 3 ) 3  and Y(PO 3 ) 3  are close to published single crystal data.
