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

Abstract

Abstract A coordination polymer [Ba 12 (btc) 8 (H 2 O) 23 ] ( 1 ) was obtained by self‐assembly of the corresponding metal carbonate with benzene‐1, 2, 3‐tricarboxylic acid ligand (H 3 btc), 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.
