Ladder-type 1D coordination polymer of Dy(iii): synthesis and investigation of magnetic behaviour

Abstract

Herein, we report the construction of a H-bonded ladder-type Dy(III) based 1D coordination polymer 1-Dy_poly using a 2,6-diacetylpyridine bis-salicyl hydrazone (H₄L) ligand system under thermal condition. The X-ray diffraction studies on the reported coordination polymer revealed that it crystallizes in a monoclinic system having the P2₁/c space group. The static and dynamic magnetic behavior of 1-Dy_poly was investigated using combined experimental and theoretical tools. The zero-field out-of-phase signals for 1-Dy_poly were observed, but with fast under-barrier magnetic relaxation processes. CASSCF-based ab initio and BS-DFT calculations were used to rationalize our experimental findings.
