The hydrothermal reactions of V2O5, HF and an organodiphosphonic acid, in the presence of appropriate templating organoammonium or metal–organic complex cations provided three new oxyfluorovanadate compounds. The V(IV) species [H3N(CH2)2NH2(CH2)2NH2(CH2)2NH3][V3O3F2(H2O){O3PCH2PO3}2]·2H2O (1·2H2O) exhibits a three-dimensional anionic framework constructed from {VO(O3PCH2PO3)}n2n− chains and {VF2O4} octahedra. The molecular structure of [N(CH2CH2NH3)3]2[NH4][V3O2F6(O3PCH2PO3)2]·2H2O (2·2H2O) is characterized by the presence of unique {V3O2F6(O3PCH2PO3)2}7− clusters. The bimetallic phase [{Cu(ophen)}VOF{HO3P(CH2)5PO3}] (3) is one-dimensional with {Cu2V2O2F2(HO3PR)2(O3PR)2} cluster building blocks.
Graphical abstractHydrothermal syntheses were used to prepare a series of vanadium oxyfluorides with organodiphosphonate linkers. A view of the one-dimensional [{Cu(ophen)}VOF{HO3P(CH2)5PO3}] is shown.Figure optionsDownload full-size imageDownload as PowerPoint slideHighlights► Hydrothermal syntheses of polyoxofluorovanadate materials. ► A novel oxyfluorovanadate cluster, {V3O2F6(O3PCH2PO3)2}7−, is described. ► A 3-D anionic framework constructed from chains and {VF2O4} octahedra. ► A 1-D bimetallic oxyfluoride [{Cu(ophen)}VOF{HO3P(CH2)5PO3}].
