Abstract

The structure of the title compound, mu-hexavanadato(V)-bis[bis(2,2'-bipyridine)nickel(II)], [(Ni(C(10)H(8)N(2))(2))(2)(V(6)O(17))], is composed of vanadium oxide layers intercalated by complex Ni(bipy)(2) cations (bipy is 2,2'-bipyridine). The structure is isomorphous with that reported recently for Zn(bipy)(2)[V(6)O(17)] [Zhang, DeBord, O'Connor, Haushalter, Clearfield & Zubieta (1996). Angew. Chem. Int. Ed. Engl. 35, 989--991]. The vanadium oxide layers are built up solely from VO(4) tetrahedra by corner sharing and clearly exhibit a sinusoidal ruffling. Two O atoms from a single vanadium oxide layer are coordinated to each Ni atom of the complex cations in a cis fashion, with Ni--O distances of 2.027 (3) and 2.087 (3) A, thus maintaining the two-dimensional structure.

摘要

标题化合物μ-六钒酸根合（V）-双[双（2,2'-联吡啶）镍（II）]，即[(Ni(C₁₀H₈N₂)₂)₂(V₆O₁₇)]的结构，由被[Ni(bipy)₂]²⁺阳离子（bipy为2,2'-联吡啶）插层的氧化钒层组成。该结构与最近报道的[Zn(bipy)₂]₂[V₆O₁₇]的结构同晶型[张、德博德、奥康纳、豪斯霍尔特、克利尔菲尔德和祖比埃塔（1996年）。《德国应用化学》英文版35卷，989 - 991页]。氧化钒层仅由VO₄四面体通过共角连接构成，且明显呈现出正弦状褶皱。来自单个氧化钒层的两个O原子以顺式与配合物阳离子的每个Ni原子配位，Ni - O距离为2.027(3)和2.087(3) Å，从而维持二维结构。
