Syntheses, structures and properties of three new two-dimensional CuI-LnIII heterometallic coordination polymers based on 2,2′-dipyridyl-5,5′-dicarboxylate ligands

Three two-dimensional CuI-LnIII heterometallic coordination polymers based on 2,2′-dipyridyl-5,5′-dicarboxylate ligands have been synthesized and IR spectra, XPS spectra and the photoluminescence spectra have been studied.
