摘要

聚合 catena-poly[2-amino-benzimidazolium [[dioxidovanadium(V)]-μ-oxido]], {(C7H8N3)2[V2O6]} n 的结构具有单斜对称性。标题化合物具有极高的抗癌活性。在晶体结构中，钒酸盐 (V2O6)2- 链是由角共享的 VO4 四面体构建而成，平行于 a 轴。两个不同的质子化 2-氨基苯并咪唑分子位于 (V2O6)2- 链之间，并与钒酸盐氧原子形成经典的 N-H⋯O 氢键，从而增强了结构的内聚力。

Synthesis and crystal structure of bis(2-aminobenzimidazolium) catena-[metavanadate(V)]

The title compound contains infinite linear zigzag vanadate (V₂O₆)²⁻chains, constructed from corner-sharing VO₄ tetrahedra, running parallel to the a axis.

The structure of polymeric catena-poly[2-aminobenzimidazolium [[dioxidovanadium(V)]-μ-oxido]], {(C₇H₈N₃)₂[V₂O₆]}_n, has monoclinic symmetry. The title compound is of interest with respect to anticancer activity. In the crystal structure, infinite linear zigzag vanadate (V₂O₆)²⁻ chains, constructed from corner-sharing VO₄ tetrahedra and that run parallel to the a axis, are present. Two different protonated 2-aminobenzimidazole molecules are located between the (V₂O₆)^2– chains and form classical N—H⋯O hydrogen bonds with the vanadate oxygen atoms, which contribute to the cohesion of the structure.

期刊介绍： Acta Crystallographica Section E: Crystallographic Communications is the IUCr''s open-access structural communications journal. It provides a fast, simple and easily accessible publication mechanism for crystal structure determinations of inorganic, metal-organic and organic compounds. The electronic submission, validation, refereeing and publication facilities of the journal ensure rapid and high-quality publication of fully validated structures. The primary article category is Research Communications; these are peer-reviewed articles describing one or more structure determinations with appropriate discussion of the science.
