摘      要：Two lanthanide selenite-carboxylate （LSC） compounds, namely, [Ln8（SeO3）4（2,6- pdc）8（H2O）10]·2H2O （Ln = Pr 1, Sm 2; 2,6-pdcH2 = pyridine-2,6-dicarboxylic acid） have been hydrothermally synthesized and structurally characterized. Both compounds possess two-dimensional layer structures constructed by Ln8（SeO3）4（2,6-pdc）8（H2O）10 clusters connected to each other via bridging carboxylate groups. The structures are further extended into three-dimensional architectures through extensive inter-layer H-bonding between coordinated water molecules and carboxylate groups. The luminescent properties and thermal stability of both compounds have been investigated.
