Homochiral 3D lanthanide camphorates with high thermal stability†
Abstract
Three isomorphous homochiral 3D lanthanide coordination polymers ([Ln(HCOO)(D-cam)]n, where Ln = Dy (1), Ho (2), Er (3)), featuring sra topology have been constructed from triple-strand helical {Ln–O}n rod SBUs and chiral D-cam spacers. Thermogravimetric analyses show the remarkable thermal stabilities of all three rigid lanthanide camphorate frameworks up to 450 °C.
