Expansion of antimonato polyoxovanadates with transition metal complexes: (Co(N _3C _5H _(15)) _2) _2[{Co(N _3C _5H _(15)) _2}V _(15)Sb _6O _(42)(H _2O)]·5H _2O and (Ni(N _3C _5H _(15)) _2)_2[{Ni(N_3C_5H_(15)) _2}V_(15)Sb_6O_(42)(H_2O)] ·8H_2O

摘要

Two new polyoxovanadates (Co-(N _3C _5H _(15)) 2) _2[{Co(N _3C _5H _(15))2}V _(15)Sb _6O _(42) (H _2O)]·5H _2O (1) and (Ni (N _3 C _5H _(15)) _2) _2 [{Ni(N _3C _5H _(15)) _2}-V _(15)Sb _6O _(42) (H _2O)]·8H _2O (2) (N _3C _5H _(15) = N-(2-aminoethyl)-1,3-propanediamine) were synthesized under solvothermal conditions and structurally characterized. In both structures the [V _(15)Sb _6O _(42) (H _2O)] ~(6-) shell displays the main structural motif, which is strongly related to the {V _(18)O _(42)} archetype cluster. Both compounds crystallize in the triclinic space group P1 with a = 14.3438(4), b = 16.6471(6), c = 18.9186(6) ?, α = 87.291(3)°, β = 83.340(3)°, γ = 78.890(3)°, and V = 4401.4(2) ? ~3 (1) and a = 14.5697(13), b = 15.8523(16), c = 20.2411(18) ?, α = 86.702(11)°, β = 84.957(11)°, γ = 76.941(11)°, and V = 4533.0(7) ? ~3 (2).
