Mixed lanthanide succinate–sulfate 3D MOFs: catalysts in nitroaromatic reduction reactions and emitting materials

Abstract

The first series of mixed succinate/sulfate/Ln MOFs, [Ln22(C22H44C22O44)22(SO44)(H22O)22] (RPF-16), where Ln = La, Pr, Nd, and Sm, were hydrothermally obtained and their structures determined by X-ray single crystal diffraction. The crystalline products are a series of isostructural 3D polymeric compounds that crystallise in the monoclinic space group P2(1)/n. Their framework comprises infinite crossing chains of LnO9 sharing edges polyhedra, kept together by succinate and sulfate anions. Topological simplification gives rise to a 3D uninodal six connected net of type pcu alpha-Po primitive cubic. These well-defined compounds show high chemoselectivity towards reduction of the nitro group and present bifunctional activity for the one-pot reductive amination of heptanal at near-complete conversion of the substrates. A general overview of the room-temperature luminescence behavior in the new RPF-16 Ln materials is also reported.
