A Tetranuclear Dysprosium Schiff Base Complex Showing Slow Relaxation of Magnetization

A tetranuclear dysprosium Schiff base complex was isolated by reacting chloride with 2-hydroxy-3-methoxybenzaldehyde and 2-(aminomethyl)pyridine in-situ under basic conditions. The Dy(III) characterized elemental analyses, single crystal X-ray diffraction molecular spectroscopy. crystallizes in the triclinic space group P-1 unit cell parameters of a = 10.2003 (4), b 13.8602 (5), c 14.9542 (6), α 94.523 (3), β 109.362 γ 99.861 (3). magnetic properties 1 have been investigated DC AC susceptibility measurements. measurements reveal weak exchange coupling antiferromagnetic nature. In measurement, shows slow relaxation magnetization absence an external field.
