Abstract

The epr of [Ru(NH₃)₅Cl]²⁺ and [Ru(NH₃)₅Br]²⁺ imbedded in single crystals of [Co(NH₃)₅Cl]Cl₂ has been investigated. The tetragonal and rhombic splittings and the orbital reduction factors were calculated from the experimental g tensors. The corrected orbital reduction factor k_ππ was estimated as 0.81 in both complexes. It was found that E(xz,yz) > E(xy), and that the tetragonal splitting is larger when the axial ligand is the chloride ion, while the rhombic is the same in both complexes. A discussion of the energy levels in terms of the π antibonding interaction is given.
