Long-lived organic cation radical species, [1I]−and [2I]−, are formed when bimetallic CoIII or VV(O) complexes of a new binucleating ligand are oxidized by one electron. The VV(O) complex, [2I]−, has a total spin, ST, of 1/2, while the robust C

An approach is suggested for using ligands to control exchange coupling in multinuclear ions. The idea arose from structural, EPR, and magnetic studies of [PPh4]3 (Scheme 1). Ferromagnetic coupling has been found between the CoII and each CoIII in 3

Radical Superexchange in Semiquinone Complexes Containing Diamagnetic Metal Ions. 3,6-Di-tert-butyl-1,2-semiquinoate Complexes of Zinc(II), Cobalt(III), Gallium(III), and Aluminum(III)

Autor: Christopher W. Lange, Brenda J. Conklin, Cortlandt G. Pierpont

Publikováno v: Inorganic Chemistry. 33:1276-1283

The tris(3,6-di-tert-butylsemiquinonato)gallium(III), -aluminum(III), and -cobalt(III) complexes have been studied structurally, spectrally, and magnetically. Complexes of the three diamagnetic metals have octahedral structures of D 3 symmetry (Ga(3,

Publikováno v: Inorganic chemistry. 36(16)

Solid state magnetic susceptibility data (2-350 K) are presented for the metal-metal doubly bonded dimers [Ru(OEP)](2) (OEP = octaethylporphyrin), [Ru(OETAP)](2) (OETAP = octaethyltetraazaporphyrin), and [Os(OEP)](2). The data are consistent with str
