A new potassium iron (III) pyrophosphate was synthesized by hydrothermal technique and characterized by X-ray studies. The compound crystallizes in a monoclinic space group,P2 1/c, with cell parameters,a = 7 365(2) Å,b = 10017(2) Å,c = 8.214(1) Å,β = 106.50(1)° andZ = 4. The structure has tunnel-type cavities and are congenial for ion transportation through them. The compound exhibits moderate thermal stability.
