Slight synthetic changes eliciting different topologies: synthesis, structure and magnetic properties of novel dinuclear and nonanuclear dysprosium complexes.
Using the Schiff-base ligand 1,5-bis(2-hydroxy-3-methoxybenzylidene)carbonohydrazide (H2hmc), dinuclear and nonanuclear compounds, [Dy2(Hhmc)2(NO3)4]·THF·MeCN (1) and [Dy9(μ3-O)4(μ-OH)6(hmc)4(NO3)4(DMF)4](OH)·H2O·THF·DMF (2) are generated through the addition of different bases, respectively. Single-crystal X-ray diffraction analysis revealed a unique Dy9 core structure of complex 2, and the magnetic properties of both compounds are fully studied.
