The title compound, {Na(H(2)O)(4)[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) 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) 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) units, bridging adjacent deca-vanadates via O=V. The structure is consolidated by an extensive network of O-H⋯O hydrogen bonds.
标题化合物{[Na(H₂O)₄]₆[V₁₀O₂₈]·2H₂O}ₙ从含有等摩尔量的偏钒酸钠和N-(2-羟基苄基)-N-(2-吡啶基)甘氨酸的水/四氢呋喃/乙腈溶液（pH约为6）中结晶得到。在晶体结构中，十钒酸盐[V₁₀O₂₈]⁶⁻阴离子（对称）通过钒中心的四个末端氧配体与两个双核[{Na(H₂O)₃}₂(μ-H₂O)₂]²⁺单元配位。这些被水合钠离子夹在中间的十钒酸盐通过μ-[{Na(H₂O)₃}₂(μ-H₂O)₂]²⁺单元相互连接形成平行于[001]的链，该单元通过O=V桥连相邻的十钒酸盐。结构通过广泛的O-H⋯O氢键网络得以巩固。
