An EPR study of Cu(2+) doped [Na(Hmal)(H(2)O)(5)] single crystals.
The magnetic environments of Cu(2+) doped Na(+) complex have been identified by electron paramagnetic resonance (EPR) technique. The angular variation of the EPR spectra has shown that two different Cu(2+) complexes are located in different chemical environments, and each environment contains one magnetic Cu(2+) site occupying substantial positions in the lattice and showing very high angular dependence. The principal g, and the hyperfine structure parameter (A) values of two sets of Cu(2+) complex groups are determined. The covalency parameter, mixing coefficients and Fermi-contact term of the complex are obtained, and the ground state wave function of the Cu(2+) ion in the lattice has been constructed.
