摘要：

Potassium organoaluminate stabilized by bidentate pyrrolyl ligand [C4H3NH(2-(CH2NHBu)-Bu-t)] was successfully synthesized and characterized. The solid state structure reveals it is a rare example of an alkyl-bridged K/Al complex, which is interlocked by bridging potassium ions to form a monodimensional polymeric array, and featured an unsupported bridging methyl interaction between potassium and aluminum metals lead to ultimate 2D supramolecular network structure. It was proved to an efficient catalyst for the conversion of CO2 into cyclic carbonates in good yields at 50 degrees C and 1 atm carbon dioxide pressure. (C) 2020 Elsevier B.V. All rights reserved.
