Synthesis and crystal structure of two [NBun4][Vv4O6(OH)(PhPO3)4] solvates
Written by sctunisie no commentsThe compounds [NBun4][V4O6(OH)(PhPO3)4]·Me2CO (1) and NBun4][V4O6(OH)(PhPO3)4]·0.5MeCN (2) have been isolated as a minor phase in the reaction of phenylphosphonyl dichloride with the mixed isopolyanion [NBun4]4V2W4O19. They crystallize in the triclinic system, space group P–1 with lattice parameters a = 12.6372(17), b = 12.6884(17), c = 19.473(2) Å, α = 104.112(12)°, β = 91.928(11)°, γ = 113.191(9)°, V = 2753.9(7) Å3, Z = 2 for 1 and a = 12.9020(5), b = 20.1755(19), c = 20.634(2) Å, α = 100.062(8)°, β = 99.696(6)°, γ = 96.159(5)°, V = 5160.9(8) Å3, Z = 4 for 2. The hybrid anion structure consists of spherical V/O/P shell of corner-sharing vanadium square pyramids and phenylphosphonate tetrahedra, encapsulating the hydroxo anion (OH-).
