Synthesis, crystal structure and spectroscopic behaviors of Co(II) and Cu(II) complexes with Salen-type bisoxime ligands

Two new complexes, {[CoL 1(MeOH)] 2(OAc) 2Co} · 2MeOH and [CuL 2] 2, have been synthesized and characterized by element analyses, 1H NMR, FT-IR and UV–Vis spectra, TG-DTA and single crystal X-ray crystallography. Crystallographic data suggests the octahedral geometry for Co(II) complex and square-py...

Description
Summary:Two new complexes, {[CoL 1(MeOH)] 2(OAc) 2Co} · 2MeOH and [CuL 2] 2, have been synthesized and characterized by element analyses, 1H NMR, FT-IR and UV–Vis spectra, TG-DTA and single crystal X-ray crystallography. Crystallographic data suggests the octahedral geometry for Co(II) complex and square-pyramidal geometry for Cu(II) complex. Furthermore, the fluorescence behavior of Cu(II) complex in DMSO is discussed. Two Salen-type ligands (H 2L 1, 4,4′-dichloro-2,2′-[(1,3-propylene)dioxybis(nitrilomethylidyne)]diphenol and H 2L 2, 4,4′-dinitro-2,2′-[ethylenedioxybis(nitrilomethylidyne)]diphenol) and their corresponding complexes ({[CoL 1(MeOH)] 2(OAc) 2Co} · 2MeOH and [CuL 2] 2) have been synthesized and characterized by element analyses, 1H NMR, FT-IR and UV–Vis spectra, TG-DTA and single crystal X-ray crystallography. Crystallographic data suggests the octahedral geometry for Co(II) complex and square-pyramidal geometry for Cu(II) complex. Furthermore, the fluorescence behavior of Cu(II) complex in DMSO is discussed.
