The title compound, Y(HP2O7)·3H2O, is isostructural with Ln(HP2O7)·3H2O (Ln = Gd, Er). The YO8 units and (HP2O7)3− anions form sheets parallel to ab and a network of O—H...O hydrogen bonds helps to establish the crystal packing.

Special details top

Refinement. The refinement was carried out against all reflections. The conventional R-factor is always based on F. The goodness of fit as well as the weighted R-factor are based on F and F2 for refinement carried out on F and F2, respectively. The threshold expression is used only for calculating R-factors etc. and it is not relevant to the choice of reflections for refinement.

The program used for refinement, Jana2000, uses the weighting scheme based on the experimental expectations, see _refine_ls_weighting_details, that does not force S to be one. Therefore the values of S are usually larger then the ones from the SHELX program.
