Synthesis and Characterization of Cobalt(II) Complexes with Diphenyl Pyraline Hydrochloride

摘要

Five new complexes of cobalt(II) with diphenyl pyraline hydrochloride (DPH) are synthesized and characterized on the basis of elemental analysis, molar conductance, magnetic susceptibility measurements, TGA, IR,1H NMR and electronic absorption spectra. The molecular structure of Co(DPH)2(H20)2cl2 complex is investigated by X-ray diffraction. This complex was screened for its fungicidal activity on A. alternaria alternata at 0.1, 0.2 and 0.3.
