Abstract
(Pb8FeFe2F24)-Fe-II-F-III is triclinic: a = 20.118(3) Angstrom, b = 5. 597(1) Angstrom, c = 9.440(2) Angstrom, alpha = 89.75(2)degrees, beta = 105.79(2)degrees, gamma = 89.38(2)degrees, Z = 2. The structure is s olved in the unconventional space group C ($) over bar 1, from X-ray s ingle crystal data using 1641 independent reflections (R = 0.048, R(w) = 0.051). It is built up from the stacking of two subnetworks along t he a axis: fluorite-like [Pb8F10](6n+)(n) layers and infinite dimetall ic [(FeFe2F14)-Fe-II-F-III](6n-)(n) double-chains of corner-sharing oc tahedra running along the b axis.
