A new rtl-type Cd(II) coordination polymer: Synthesis, structure, luminescent property, and topology analysis

ABSTRACT

A new Cd(II) coordination polymer, namely [Cd₃(BPT)₂(μ₂-H₂O)₂(H₂O)₂]_n (1 H₃BPT = biphenyl-3,4′,5-tricarboxylic acid), was obtained via the solvothermal reactions of Cd(NO₃)₂ and H₃BPT. Single-crystal X-ray structural analysis reveals that compound 1 crystallizes in monoclinic P2₁/c space group and features a 3D framework based on trinuclear [Cd₃(COO)₄(μ₂-H₂O)₂] subunits. Topological analysis reveals that compound 1 represents a (3,6)-connected rtl topological network. In addition, the thermal stability and luminescent property of 1 were also investigated.
