Abstract

Title full: Reactions of polyoxomolybdates with oximes. The crystal and molecular structures of [(C₄H₉)₄N]₂[Mo₂O ₅C₆H₄(O)CHNO₂] · CH₂Cl₂ and [(C₄H₉)₄N]₂[Mo₂O ₅C₆H₅CH(O)C(NO)C₆H₅₂]. The reactions of [(C₄H₉)₄N]₂[Mo₂O ₇] with the oximes benzoinoxime and salicylaldoxime yielded the complexes [(C₄H₉)₄N]₂[Mo₂O ₅C₆H₄(O)CHNO₂] · CH₂CI₂(7) and [(C₄H₉)₄N]₂[Mo₂O ₅C₆H₅CH(O)C(NO)C₆H_{5 2}] (8). The structures of 7 and 8 exhibit the [Mo₂O₅]₂₊ core with the oximato moieties of the ligands functioning as μ₂-O,N bridging donors. The metrical parameters are consistent with the sp² hybridization of the oximato nitrogen with double bond character localized on the C{single bond}N bond. Crystal data: Compound 7, monoclinic space group, P2₁/c, a = 16.271(6), b = 14.010(4), c = 25.390(8) Å, β = 101.34(2)°, V = 5672.9(19) Å³, D_calc = 1.30 g cm^-3 for Z = 4. Structure solution and refinement based on 4718 reflections with F_o ≥ 6σ(F_o)(Mo-K_α, λ = 0.71073 Å) converged at a conventional residual of 0.064. Compound 8, rhombohedral space group (hexagonal setting) R over(3, -), a = b = 47.188(14), c = 15.766(3) Å, V = 30403.4(27) Å³, D_calc = 1.19 g cm^-3 for Z = 18. Structure solution and refinement based on 3015 reflections with F_o ≥ 6σ(F_o) converged at a value of 0.069 for the conventional R factor. Reaction of the related salicylhydroxamic acid with [(C₄H₉)₄N]₂[Mo₂O ₇] in methanol yielded the complex [(C₄H₉)₄N][MoO₂C₆ H₄(OH)C(O)NOC₆H₄(OH)C(O)NHO] (11), a species exhibiting both hydroximato(2-) and hydroxamato(1-) forms of the ligand. Crystal data: Compound 11, monoclinic space group P2₁/c, a = 10.261(2), b = 17.864(4), c = 18.270(3) Å, β = 91.98(1)°, V = 3347.0(10) Å³, D_calc = 1.34 g cm^-3 for Z = 4. Structure solution and refinement based on 3406 reflections converged at a value of 0.049 for the conventional R factor.
