摘要：

While organic-inorganic hybrid vanadium oxides, polyvanadate clusters and vanadium complexes have been extensively studied[1-3], the construction of microporous two-dimensional and three-dimensional vanadium coordination polymers by bridging organic ligands remains relatively unexplored[4], and hence further model complexes are required to understand the coordination nature of vanadium. We report here two isomorphous vanadium coordination polymers formulated as[VO(DBOD)2]X2(DBOD=l,4-diazoniabicyclo[2,2,2] octane-l,4-diacetate, X=Cl or Br). Crystal structural analysis shows that they are the first examples of non-cluster-type vanadium coordination polymer constructed from VO5 square-pyramidal units. DODB in μ2-niode along[110] and[1-10] directions links two adjacent two vanadium ions,Which resulting in double wave-like two-dimensional layers with 36-memered saddle-shaped rings (ca. 12.0×6.2 Å) As can be seen from the three-dimensional stacking array (Fig. 1), the adjacent two layers stack in a crossed laminating fashion giving rise to approximate square channels (ca. 6.2×6.2 Å) along c-axis direction.
