The crystal structures of three ammonium vanadium diphosphates have been investigated by means of X-ray powder diffraction including ab initio structure determination and Rietveld refinement. The compound NH 4 VP 2 O 7 crystallizes in the monoclinic space group P2 1 /c with a β«Ψβ¬ 7.5149(2) A s , b β«
## Abstract **Summary:** The fullβprofile refinement of Xβray diffraction patterns was used to investigate two poly(thiodiethylene terephthalate) (PSDET) samples with different thermal history in order to thoroughly analyze their polymorphic aspects. In each sample, a crystalline (__Ξ±__ or __Ξ²__) a
