Synthesis, Crystal Structure, and Physical Properties of a ­Barium(II) Benzene-1, 2, 3-tricarboxylic Acid Complex

A coordination polymer [Ba12(btc)8(H2O)23] (1) was obtained by self‐assembly of the corresponding metal carbonate with benzene‐1, 2, 3‐tricarboxylic acid ligand (H3btc), and its structure was determined by single‐crystal X‐ray diffraction studies. The results revealed that complex 1 has a three dime...

Description
Summary:A coordination polymer [Ba12(btc)8(H2O)23] (1) was obtained by self‐assembly of the corresponding metal carbonate with benzene‐1, 2, 3‐tricarboxylic acid ligand (H3btc), 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 btc3– anions adopt four different conformation and coordination modes. Bridging btc3– anions and μ2‐bridging water molecules connect BaII ions to generate a two dimensional layer. Further, μ2‐bridging coordinated water molecules connect the BaII ions of neighboring layers to form a three dimensional structure. Additionally, the luminescent property and thermal stability of 1 were investigated.
