摘要: The synthesis and characterization of a copper(I) complex containing two-coordinated chelating verdazyl radicals are described. structure (shown) consists distorted tetrahedral geometry at the copper ion; angle between planes defined by two rings is nearly 116°. Variable-temperature magnetic-susceptibility data for complexes were obtained, analysis which revealed very weak intramolecular magnetic coupling radicals.
