Synthesis, Crystal Structure, and Emission Spectra of Lanthanum(III) Coordination Polymer with 1,5-Naphthalenedisulfonate Ligand
Abstract
The first two-dimensional lanthanum(III) coordination polymer, [La(1,5-NDS)1.5(H2O)5]n (1) (1,5-NDS2− = 1,5-naphthalenedisulfonate), was synthesized and structurally characterized by single-crystal X-ray diffraction analysis. The disulfonate ligands act in the η1:η1:μ2 and η1:η1:η1:μ3 binding modes to link the LaO9 tricapped trigonal prisms into a lamellar structure. It exhibits strong purple emission in the solid state.
