EPR spectra of Cu2+ and VO2+ ions in tetraaquabis (pyridine) Co(II) saccharinate tetrahydrate ([Co(H2O)4(py)2](sac)2·4H2O) single crystals
2009
Abstract Cu 2+ and VO 2+ doped tetraaquabis (pyridine) Co(II) saccharinate tetrahydrate single crystals have been studied at room temperature and at 113 K in three mutually perpendicular planes using EPR. Both ions yield unexpectedly large number of EPR lines. The angular variation of the EPR spectra has shown that two different Cu 2+ and VO 2+ complexes are located in different chemical environments and each environment contains one magnetically inequivalent Cu 2+ and VO 2+ sites in distinct orientations occupying substitutional positions in the lattice.
