Molecular structure and EPR spectra studies of saccharinate complexes with 4-acetylpyridine
Özet
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. (C) 2012 Elsevier Ltd. All rights reserved.
