Abstract

Single crystals of a novel organic-inorganic framework [Fe0.28V0.72OH0.8(NH4)0.2(C8H4O4)] · 0.53(C8H6O4), 1, have been prepared by hydrothermal synthesis in the presence of an oxidizing agent. The structure was solved by single crystal X-ray diffraction: space group Pnma, a = 17.6956 (19) Å, b = 6.8745 (7) Å, c = 11.9303(12) Å. The three dimensional framework is constructed from Fe/V-O chains that are cross-linked by 1,4-benzene dicarboxylate (BDC) anions forming large one-dimensional channels. As synthesized, the compound contains additional dicarboxylate groups occupying disordered positions in the channels that can be removed by heating. The chemical reactivity of 1 and its magnetic properties are reported. The new phase is closely related to analogous Cr (III) and V(III) phases recently reported by Férey and co-workers.
