Two New Coordination Complexes Based on Eosin Y Dye Ligand: Syntheses, Crystal Structures and Magnetic Properties

摘要

Two novel coordination compounds formulated as [Co2(EY)2(L1)]·2C2HsOH (1)and [Mn2 (EY)2(L1)]·2C2H5OH (2) (EY =Eosin Y dianion,L1 =4,4'-bipyridine) based on Eosin Y dye ligand have been prepared by solvothermal reactions and structurally characterized.Single-crystal X-ray diffraction studies reveal that compounds 1 and 2 are isostructural.They show weak antiferromagnetic coupling between the adjacent CoⅡ and MnⅡ ions,respectively.
