✦ Synopsis


Fe III (H 2 O)(O 3 P-(CH 2 )-CO 2 )] or MIL-49 was hydrothermally synthesized under autogenous pressure at 1701C for 48 h. Its bidimensional structure was solved from single-crystal X-ray diffraction in the monoclinic space group P2 1 /c (No.14). Cell parameters are a = 9.3836(3) A ˚, b = 6.3798(3) A ˚, c = 10.1371(3) A ˚, b = 111.891(2)1, Z = 4, and V = 563.10(4) A ˚3. Reliability factors of the structure refinement are R 1 (F) = 0.0470 and wR 2 (F 2 ) = 0.1297 for 1036 reflections with I42r(I). The structure of MIL-49 is based on inorganic units built up from two edge-sharing [FeO 5 (H 2 O)] octahedra and two carboxymethylphosphonate groups. The connection of these units leads to the formation of hybrid sheets. A dangling oxygen atom from the carboxy function points toward the interlayer space and is responsible for hydrogen bonding with adjacent layers. Magnetic measurements and 57 Fe Mo¨ssbauer study reveal an antiferromagnetic ordering below T N = 25(1) K which becomes canted below 11(1) K.
