The crystal structures of [Co(4-acpy)2(H2O)4] (sac)2 (1) and [Zn(4-acpy)2(H2O)4] (sac)2 (2) (4-acpy: 4-acetylpyridine, sac: saccharinate) complexes have been investigated by X-ray diffraction techniques. The magnetic environments of Cu2+ doped [Co(4-acpy)2(H2O)4] (sac)2 and [Zn(4-acpy)2(H2O)4] (sac)2 complexes have been identified by electron paramagnetic resonance (EPR) technique. Principal values of g and hyperfine tensors are determined and the ground state wave functions of Cu2+ ions are obtained using EPR parameters. The vibrational spectra were also discussed in relation with the other compounds containing saccharinate and 4-acetylpyridine complexes.
