Abstract

The electron paramagnetic spectra of trigonal Mn2+ centers in [Co(H2O)6]SiF6, [Co(H2O)6] SnF6, and [Co(H2O)6]PtCl6 crystals were studied on the basis of the complete energy matrices for a d5 configuration ion in a trigonal ligand field. When Mn2+ is doped in the [Co(H2O)6]SiF6, [Co(H2O)6]SnF6, and [Co(H2O)6]PtCl6 crystals crystals, there is a similar local distortion. The experimental results show that the local lattice structure around a trigonal Mn2+ center has an elongation distortion along the crystalline C3 axis. From the EPR calculation, the local lattice structure parameters R=2.278A, θ=52.6406° for [Co(H2O)6]SiF6, R=2.280, θ=52.4936° for [Co(H2O)6]SnF6 and R=2.244A, θ=53.0616° for [Co(H2O)6]PtCl6 were determined.
