Abstract
A new two-dimensional (2D) polymer, [Ag(2-Clnic)]n (2-Clnic = 2-chloronicotinate) (1), has been synthesized and characterized by IR, elemental analysis, single-crystal X-ray diffraction, and luminescence spectroscopy. X-ray crystal analysis reveals that complex 1 is constructed through π-π stacking and Ag…O interactions, which provide important roles in the assembly of intriguing structures and specific photophysical properties. In the solid state at room temperature, 1 is found to be luminescent with a purple emission band at 411 nm upon excitation at 360 nm.
