摘要：
Cu2+ and VO2+ 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 Cu2+ and VO2+ complexes are located in different chemical environments and each environment contains one magnetically inequivalent Cu2+ and VO2+ sites in distinct orientations occupying substitutional positions in the lattice.
