چکیده انگلیسی


• Two novel 2D lanthanide sulfate frameworks were prepared under hydrothermal reactions.
• The two polymers bear a rare quasi-honeycomb metal arrangement.
• The two compounds display excellent thermal stability.
• The two compounds display characteristic terbium and dysprosium luminescence.

Two novel lanthanide−sulfate compounds, [Ln2(SO4)3(H2O)8] (Ln = Tb (1) and Dy (2)), have been synthesized under hydrothermal reactions. X-ray crystal structure analyses reveal that 1 and 2 are isomorphous and crystallize in monoclinic C2/c pace group, showing a layered structure. The layers bear a rare quasi-honeycomb metal arrangement, which is fastened by μ3 = η1:η1:η1 and μ2 = η1:η1 sulfates. If assigning the μ3 = η1:η1:η1 sulfate as a 3-connected node and the Ln3+ ion as a 4-connected node, the network can be rationalized as a binodal (3,4)-connected V2O5 topology with a Schäfli symbol of (42·63·8) (42·6). In addition, the infrared, thermogravimetric analysis and luminescent properties were also studied. Complexes 1 and 2 exhibit outstanding thermal stability and characteristic terbium and dysprosium luminescence.

Two novel 2D lanthanide sulfate frameworks [Ln2(SO4)3(H2O)8] (Ln = Tb and Dy) have been synthesized successfully, which bear a rare pseudo-honeycomb metal arrangement and display excellent thermal stability. The metal arrangement is fastened by μ3 = η1:η1:η1 and μ2 = η1:η1 sulfates. Moreover, they displays characteristic terbium and dysprosium luminescence, respectively.Figure optionsDownload as PowerPoint slide
