Crystal Structure and Luminescent Property of 2D Hybrid Silver Chloride with 1,2-Bis(4-pyridyl)Ethane

Using the flexible dipyridyl ligand 1,2-bis(4-pyridyl)ethane (bpe), a hybrid silver chloride Ag3Cl3-(bpe)2]n(1) has been synthesized by ultrasonic method. The experimental results indicate that it belongs to triclinic system with space group P1. The structure of complex 1 features 1D (Ag6Cl6)n chains, which are further linked by bipodal spacers bpe to form a 2D bilayer structure. In addition, the complex 1 shows a strong yellow emission band that peaks at 525 nm (λex=385 nm) in the solid state at room temperature, and it is thermally stable below 170 ℃.
