Complexes of Cobalt(II) Iodide with Pyridine and Redox Active 12-Bis(arylimino)acenaphthene: Synthesis Structure Electrochemical and Single Ion Magnet Properties

摘要

Complexes [(dpp-BIAN) Co I ]·MeCN ( ) and [(Py) CoI ] ( ) were synthesized by the reaction between cobalt(II) iodide and 1,2-bis(2,6-diisopropylphenylimino)acenaphthene (dpp-BIAN) or pyridine (Py), respectively. The molecular structures of the complexes were determined by X-ray diffraction. The Co(II) ions in both compounds are in a distorted tetrahedral environment (CoN I ). The electrochemical behavior of complex was studied by cyclic voltammetry. Magnetochemical measurements revealed that when an external magnetic field is applied, both compounds exhibit the properties of field-induced single ion magnets.
