Ionothermal synthesis of two oxalate-bridged lanthanide(iii) chains with slow magnetization relaxation by using a deep eutectic solvent†
Abstract
Two novel isostructural oxalate-bridged lanthanide(III) chains, (choline)[Ln(ox)(H2O)3Cl]Cl·H2O (Ln = Dy/Er), were first obtained ionothermally by using a choline chloride–oxalic acid eutectic mixture as both solvent and structure-directing agent, both of which show field-induced slow relaxation of magnetization.
