| description | A dicompartmental Schiff base ligand was synthesized and used for the assembly of a lanthanide grid-like complex. Dinuclear <b>Dy<sub>2</sub></b> and tetranuclear <b>Dy<sub>4</sub></b> complexes were isolated from the reaction of the ligand with different dysprosium salt. Single crystal X-ray diffractions show that the two Dy<sup>III</sup> ions in <b>Dy<sub>2</sub></b> are adopted in the N<sub>3</sub>O coordination pockets of the ligand and further coordinated by water molecules, whereas, for <b>Dy<sub>4</sub></b>, the four Dy<sup>III</sup> ions are clamped by four ligands through their terminal N<sub>3</sub>O coordination pockets, forming a grid-type assembly. Magnetic studies reveal that complex <b>Dy<sub>2</sub></b> shows field-induced single-molecule magnetic behavior under 1000 Oe dc field, complex <b>Dy<sub>4</sub></b> shows fast relaxation under zero field and field-induced single-molecule magnet (SMM) behavior under 500 Oe. The difference in the magnetic relaxation is related to the various deprotonation of the ligand and distinct topology of the assemblies. |
