Bismuth(V) iron(III) tris(phosphate) oxide.
Bi(V)(0.4)Fe(3)(III)O(PO(4))(3) crystallizes with two Fe atoms (one on an inversion centre and one on a mirror plane) displaying octahedral geometry and a third Fe atom (on a mirror plane) with trigonal bipyramidal coordination. Fe atoms are seen in oxygen-bridged chains. Bi(V) atoms are found in the interstitial sites between these chains. Bi shows sevenfold coordination, with Bi-O distances between 2.357 (7) and 2.529 (6) A.
