AbstractNowadays, the preparation and structural elucidation of lanthanide coordination polymers have gained significant attention for their fascinating architectures, topology and potential application in a wide variety of areas [1,2]. On the one hand, aromatic polycarboxylic acid ligands, or its derivatives are frequent choices for coordination polymers, because of their versatile coordination sites. Among the aromatic acids, 5-sulfoisopthalic acid (SIP) ligand has one sulfonate group and two carboxylate groups, which could be useful in the construction of a new Ln(III)-organic coordination polymers (Fig. 1). On the other hand, Ln(III)-based coordination polymers are stimulating more and more research because of their potential applications in fluoroimmunoassays, spectroscopic structural probes, laser systems, organic light-emitting diodes, biological systems, optical amplification, single-molecule magnets and sensors [3–6]. Among all Ln-CPs, the Nd-CPs are important luminescent centres because they exhibit strong emission peaks in the NIR region. Thus, Nd(III)-containing structures have been regarded as the most popular NIR luminescent materials for application in telecommunication and laser systems [7].
