Hexakis(tetraaquasodium) decavanadate(V) dihydrate
نویسندگان
چکیده
The title compound, {[Na(H(2)O)(4)](6)[V(10)O(28)]·2H(2)O}(n), crystallized from a H(2)O/THF/CH(3)CN solution (pH ca 6) containing equimolar amounts of NaVO(3) and N-(2-hydroxy-benz-yl)-N-(2-picol-yl)glycine. In the crystal structure, the deca-vanadate [V(10)O(28)](6-) anion ( symmetry) is coordinated, via four terminal oxide ligands of V centres, to two dinuclear [{Na(H(2)O)(3)}(2)(μ-H(2)O)(2)](2+) units. Inter-connection of these aquasodium-ion-sandwiched deca-vanadates to chains parallel to [001] is effected by μ-[{Na(H(2)O)(3)}(2)(μ-H(2)O)(2)](2+) units, bridging adjacent deca-vanadates via O=V. The structure is consolidated by an extensive network of O-H⋯O hydrogen bonds.

In the title compound, (C(5)H(7)N(2))(6)[V(10)O(28)]·2H(2)O, the [V(10)O(28)](6-) anion is generated by crystallographic inversion symmetry and each of the five vanadium centres adopts a distorted VO(6) octa-hedral geometry. In the crystal structure, a network of N-H⋯O, N-H⋯(O,O) and O-H⋯O hydrogen bonds helps to establish the packing.
