Abstract

The hydrothermal reactions of NH 4VO 3 with the aromatic phosphonate ligands 1,4-, 1,3-, and 1,2-phenylenediphos-phonic acids (H 4LI, H 4L3, H 4L4, respectively); biphenyl-4,4′-diyldiphosphonic acid (H 4L2); and 1,3,5-tris(phenyl)-4,4′-triphosphonic acid (H 6L5) yielded materials of the V xy/organophosphonate family [VO(H 2L1)] (1), [VO(H 2L2)] (2), [V 2O 2(H 2O) 2(L3)] ·1.5H 20 (3·1.5H 2O), [V 2O 2(H 2O) 2(L4)] ·; 2H 2O (4·2H 2O), and [V 3O 3(OH)(H 3LS) 2]·7.5H 2O (6 · 7.5H 2O). The reactions were carried out in the presence of HF, and in one case, fluoride was incorporated to provide [V 2F(OH)(H 2O) 3(L4)] ·; 2.25H 2O (5·2.25H 2O). The materials exhibit diverse structural chemistry, including the prototypical buttressed layer architecture for 1 and 2, a complex three-dimensional structure for 3, and unique two-dimensional structures for 4, 5, and 6. The structures of this oxovanadium-arylphosphonate family are quite distinct from those previously described for the V xO y/alkyldiphosphonate series.
