Pb3[C6(CH3)3(CO2)3H6]2[DMF]3: first layered Pb-Kemp's triacid complex†
Abstract
An unprecedented layered Pb-Kemp's triacid compound, Pb3[C6(CH3)3(CO2)3H6]2[DMF]3, has been synthesized. The material exhibits a selective CO2 adsorption, a reversible DMF coordination, and an intercalative hexanal addition reaction. A competing crystallization reaction under solvothermal conditions using Pb2+ and Cd2+ with Kemp's triacid reveals higher selectivity of Cd2+ over Pb2+.
