Synthesis, Crystal Structure, and Luminescence of Three-dimensional Cd(II) Coordination Polymer Generated from Benzopenone-2,4′-dicarboxylate and 1,4-Bis(1H-imidazol-1-yl)butane Mixed Ligands

Аннотация

A new coordination polymer, namely, [Cd(L)(BIB)_0.5]_n (H₂L = benzophenone-2,4′-dicarboxylic acid, BIB = 1,4-bis(1H-imidazol-1-yl)butane), was synthesized under hydrothermal condition. Single-crystal X-ray analysis reveals that two adjacent Cd(II) ions are bridged by four L²⁻ ligands to form a two-dimensional layers, which are further connected by BIB to build a beautiful three-dimensional (3D) network. The luminescent and thermal properties of the compound are investigated.
