Novel Linking Ligand Containing Sulfur-Donor Atoms and Its Compounds of Palladium and Silver

摘要

A linking ligand containing sulfur donor atoms in the terminal thiophene rings, 1,2-bis(thiophen-2-ylmethylene) hydrazine (L), was prepared by Schiff-base condensation. Ligand L reacted with [PdCl₂(NCPh)₂] to produce a molecular Pd compound [PdL₂Cl₂] (1). On the other hand, it reacted with AgNO₃ and AgClO₄ to produce a 2-D network [AgL_0.5(NO₃)] (2) and a 1-D polymer [AgL]ClO₄ (3), respectively, whose structures are based on secondary intermolecular forces such as H-bonding, van der Waals interaction, and ヰ-ヰ stacking. Polymer 2 exhibited photoluminescence at room temperature in the solid state.
