Synthesis, Structure, Photoluminescence Property of a Barium Complex With Sulfosalicylic Acid Ligand

Abstract

A new coordination polymer [Ba(hssal)]_n(1) (H₂hssal: 5-sulfosalicylic acid) was obtained by self-assembly of BaCO₃ with ligand 5-sulfosalicylic acid dihydrate (H₂hssal·2H₂O), and its structure was determined by single-crystal X-ray diffraction. Complex 1 has a three-dimensional (3-D) network structure, and each hssal^2– ligand coordinates with Ba(II) atom, and both use carboxylate groups adopting syn-μ₂ – η¹ : η¹ bridging coordination mode and sulfonate group taking μ₃-bridging coordination mode. The coordination geometry around the Ba1 atom is a distorted dicapped triangular prism. The luminescence property of 1 was investigated, and it was found that the complex showed photoluminescence in the solid state at room temperature.
