An Azido‐Bridged Dysprosium Chain Complex Showing Zero‐field Slow Magnetic Relaxation.

A one‐dimensional (1D) azido‐bridged dysprosium coordination polymer featuring a zig‐zag chain structure constructed from a halogen‐functionalized quinoline derivative and N3− ligands was structurally and magnetically characterized. Magnetic studies revealed that the chain complex exhibits zero‐field slow magnetic relaxation and a significant butterfly‐like hysteresis loop, originating from highly magnetic anisotropy of the Dy3+ ions in a D4d symmetry. This compound represents the first azido‐bridged lanthanide chain showing zero‐field slow magnetic relaxation behavior. These results highlight that the combination of high symmetric Ln3+ ions with the versatile azido bridging ligand provides an effective approach for the design and construction of advanced lanthanides molecular magnets.
