摘要

A coordination polymer [Ba _(12)(btc) _8(H _2O) _(23)] (1) was obtained by self-assembly of the corresponding metal carbonate with benzene-1, 2, 3-tricarboxylic acid ligand (H _3btc), and its structure was determined by single-crystal X-ray diffraction studies. The results revealed that complex 1 has a three dimensional structure. In 1, the btc ~(3-) anions adopt four different conformation and coordination modes. Bridging btc ~(3-) anions and μ _2-bridging water molecules connect Ba ~(II) ions to generate a two dimensional layer. Further, μ _2-bridging coordinated water molecules connect the Ba ~(II) ions of neighboring layers to form a three dimensional structure. Additionally, the luminescent property and thermal stability of 1 were investigated.
