摘要：
Chevreul's salt, a mixed valence copper sulfite Cu-3(SO3)(2). 2H(2)O, was synthesized by a reaction between CuSO4 and NaHSO3, and characterized by X-ray photoelectron spectroscopy, magnetic susceptibility, EPR and electronic spectroscopy. These magnetic and spectroscopic studies consistently proved the validity of the formulation (Cu+)(2)SO3Cu2+SO3(H2O)(2). Between Cu+ and Cu2+ ions an intervalence transition occurs with an energy of 23 500 cm(-1). (C) 1999 Elsevier Science S.A. All rights reserved.
