New Coordination Mode of 5-Aminoisophthalate in Lead Coordination Polymers: Synthesis, Structure, and Photoluminescence Properties

A new lead coordination polymer [Pb(aip)]n (H2aip = 5-aminoisophthalic acid) was synthesized and characterized by IR,elemental and X-ray single-crystal analyses. X-ray crystallographic study of this complex revealed that H2aip ligand adopts a new coordination mode different from any reported modes in the title complex. The thermogravimetric experiment was carried out to examine the thermal stability, and the photoluminescence property of the title complex was investigated.
