摘要
Two new three-dimensional lanthanide-alkali-heterometallic frameworks assembled from Ln(III) (Ln = Sm, Dy), Na(I), and isonicotinic acid ligand, formulated as [NaLn(IN)(3)(NO3)] (n) (Ln = Sm(1), Dy(2), IN- = isonicotinic acid)], were obtained as single phases under hydrothermal conditions. Compounds 1 and 2 are isostructures with three-dimensional frameworks, which are the rare examples of lanthanide-alkali-heterometallic compounds. The band gaps calculated from adsorption spectra reflect their semiconductor natures. Strong luminescence in two compounds can be attributed to the emissions involved in Ln(3+) centers.
