Phosphatovanadium chemistry: New compounds, including an example of tenne's prospect , and oxidation of cyclohexadiene

Reactions of various vanadyl (Vv) compounds with silyl phosphate, phosphonato, or alkyl phosphate compounds have provided the cluster compounds (VO)6(O3POSiMe3)8Cl (1), [Et4P]+[(V2O3)2(O 3PPh)4F]- (2), and the methylphosphonato and butyl phosphate analogues of compound 2. Both compounds 1 and 2 oxidize 1,4-cyclohexadiene to benzene, and the reduction product of the methylphosphonato analogue of compound 2 has been characterized as [Et4P]+1.5 [(4-tert-butylpyridine)2H]+0.5 [(V2O3)2(MePO3)4F] 2- (3). In the mixed-valence compounds 1 and 3 the odd electron is determined by EPR spectroscopy to be localized on a single VO unit in compound 1 and delocalized in compound 3. Compound 1 crystallizes in the tetragonal space group I4/m with cell constants (at -100°C) a = b = 13.788(2) A?, c = 19.126(3) A?, V = 3636(1) A?3, Z = 2; compound 2 crystallizes in the triclinic space group P1 with cell constants (at -70°C) a = 12.541(5) A?, b = 13.177(4) A?, c = 14.761(5) A?, α = 83.26(4)°, β = 68.91(4)°, γ = 72.23(3)°, V = 2167(1) A?3, Z = 2; compound 3 crystallizes in the orthorhombic space group Iba2 with cell constants (at -100°C) a = 17.462(3) A?, b = 33.787(6) A?, c = 14.623(2) A?, V = 8627(2) A?3, Z = 8. Features common to all compounds are the encapsulated halide ion and the role played by the phosph(on)ato moieties: by allowing only three oxygen atoms per phosphorus to participate in cluster bonding, the phosphorus centers become sites of positive Gaussian curvature and support closure into polyhedral structures. Compound 1 realizes Tenne's prospect of expressing a layered structure, in this case α-VOPO4, in closed polyhedral form.
