Abstract This paper describes the synthesis and the structure determination of [V 2 PO 8 F] 2- , [C 2 N 2 H 10 ] 2+ ( en ), the first oxyfluorinated vanadophosphate with an open framework structure. V 2 PO 8 F, en crystallizes in the acentric P 2 1 2 1 2 1 (No. 19) space group with cell parameters a = 8.2939(6) A, b = 9.2260(8) A, c = 12.5021(8) A V = 956.7(2) A 3 , Z = 4. The structure consists of chains of alternating VO 6 octahedra and PO 4 tetrahedra in the [001] direction. These chains, located at y ≈ 0 and 1 2 , are linked by VO 5 square pyramids at y ≈ ± 1 4 levels in such a way that the two types of corner-sharing vanadium polyhedra form zigzag chains along the [100] direction. This framework defines 10-membered windows in the (110) and (1 - 10) planes and 10-membered zigzag tunnels along [001] inside which the diprotonated ethylenediamine is located.
