• Variable-temperature dc magnetic susceptibility shows weak long-range order of chain of magnetization.
• The dynamic susceptibility exhibits a typical of SMM behavior.
• The Cole–Cole curves show the presence of at least two relaxation processes at a low temperature.
• We report a Salen-type dysprosium complex that represents pure 4f SIMs with 1D ionic coordination network.
A new flexible Salen-type dysprosium coordination polymer, e.g. {[Dy2(H2L)4Cl4(CH3OH)2]Cl2·CH3OH}n (1) (H2L = N,N′-bis(salicylidene)-1,4-butane-diamine), is afforded by the reaction of H2L with DyCl3·6H2O. X-ray crystallography analysis reveals that complex 1 features one-dimensional (1D) ionic double-chain structure. Magnetic studies suggest that the coordination polymer exhibits a typical SMM behavior under an external magnetic field.
